I apparently scaled a parking garage, climbed in at the third story and peed against a car when my concerned friends came to get me. I have no recollection of the actual climbing or peeing. This was back when I was about 16 years old and just old enough to be drinking lots and lots of beer...

Oh and I ate a full bowl of 'mon cheri' chocolates while watching TV when I was about 4 or 5 years old which made me very very drunk, when my parents went skiing while thinking I was asleep.
