Mine are all the typical ones that you mentioned,

Transferring my job, finding a new apartment, applying for grad school and uprooting my kids from the only town they've ever known to move them 200 miles away from family to a city they didn't know; all within one month! They still have not forgiven me for it and that was over 5 years ago. I confused love with mania.

Ok..the strangest I have done....was married at the time but hubby was on deployment. I went on a cleaning spree in the middle of the night...mostly in the kitchen...pulled the fridge out to clean behind it...ran outta steam and had to go across the hall and get my neighbor to put it back for me at 5am before he went to work. I felt like such a dumbass!

probably not the craziest but the one I think was the most fun:

while driving down a highway at 70MPH, I crawled out of the drivers side passenger window across the roof and into the front seat of the passenger side of the car.

I bought some plastic flamingos and hot glued a Santa Claus hat and beard on one of them. On the other I hot glued a Mrs. Claus hat and wire spectacles. I put them in my front yard. It was June.

Mine are pretty typical - sex,drugs,rockandroll,..crazy dangerous stuff I'm suprised I'm still alive.

On one occasion I decided we needed a bathroom in our basement and broke up all the concrete floor for it over a night.. I did however finish that project, took a year but the bathroom is really nice.

We adopted 1 ferret from a family member. Which started me on another manic collection. I brought in a total of 12. We tried to keep up for almost 2 years...OMG what a chaotic mess.
Then I developed a wig obsession.
Then pillow collecting. And we can go on & on.

Everyone knows mine, lol - they got pretty "boring" after I hit mid-adulthood (well, mostly), but the time where I tried to prove to the local news crew that trees talked audibly in response to music (this after already being written up positively for restoring a city garden) was pretty bizarre....

I don't do much while manic anymore, just take bus rides across the country. Once I thought I could fix all the water (and health) problems in a central American country and went to Manic lengths to tell them about it...

Jumping onto moving trains or trying to foil the plans of imaginary drug lords just sounds so Far Off anymore...does that mean I'm Old?

(and, Jesus - I wish Patrick would respond to this with some of his Milder stories...gah)

I don't think I've ever really done anything too crazy or interesting. I am fond of cleaning and re-organizing things in the middle of the night when I get some sort of burst of 'inspiration'. I once made curtains at 3am on a whim.

In my younger days, I did flash my boobs at passing cars on a street corner in the middle of the night, thinking it was really funny. I was with a friend and what ended up happening was we were mistaken for hookers and I got the police called on me by some lady who stopped, but I ran away before they got there....lol And yes, I was totally sober, just completely manic and high on life. I guess I wanted to pretend it was Mardi Gras even if it was summer and I live in California....lol

I walked half way across a semi frozen river (well it was the inlet from the river to the bay and was in town, it was probably 8 feet deep, and 25 feet across. Had a foot bridge over top)

Anyways, i walked to the middle to write my name in the snow on the ice, so that everyone who crossed the foot bridge, would see my name. Needless to say, River never really freeze over, as the rushing water beneath keeps it from freezing more than a couple of inches. I got.. M.... A... R... and at the Y..... the ice and snow around me in a circle started turing black.... I was sinking.

It was like.... being seriously HIGH and then getting pulled over by the cops. BIG REALITY CHECK. THEN, when I ran over to the edge to get up (5 foot breakwall) I couldnt get up..... I had to wait till a stranger came by and saw me there, and I asked for help.

Fuct-up-est think Ive ever done while manic.

I think the worst two things I did while manic, was trying to set my on fire in apartment. Hubby came home and found me in the walk in closet screaming that the cat pissed on my clothes. Another one was when I took a broom and tried to kill my hubby with it. I about made him jump two stores to get away. He finally physically stopped me and went to the magistrate and got me commited. The rest are pretty typical actions

i feel a lot of shame about most of the stuff i did when manic. i try not to even think about it - which never really works. not anything funny i think

Besides the sex and drugs issues I got married, I had kids all while hypomanic or depressed. Had grandiose ideas of parenthood and all that. Was a real bitch to my kids and didn't treat them right emotionally abusive parent. My hubby said the weirdest thing I've done was sit straight up in bed and talk to his mother.....after her death. Mostly though my behaviour had to do with mostly sex and some drugs more sex than drugs. Oh and I had an affair with a married guy who later suicided we think (can't be proven either way) and who in retrospect was also bipolar I think. I was not married at the time but it was my hubby's best friend who was married at the time.

when i am manic, i shoplift a lot. its not that i am pressed to have things I cannot afford, but in this state,i thrive on my impulsive and risky behavior. Also, i do a freaking lot of drugs when im in this state. Now, when i come down into my normal mood, you would never guess half the things I have done because I can barely remember.

Well besides the drugs and alcohol thing...

I have a tendency to drive with absolutely no destination during the night when I'm manic and can't sleep, then the manic starts to grow more rapidly and I start to consider finding 24 hour tattoo shops...

...That's when I use my logical side, take a milligram of Xanax, head home, crawl into bed with my guy and start crying. (I'm an extremely rapid cycler)

That's without a doubt not the "craziest" thing I've ever done while manic... just how my most recent episodes have played out.
