1 - Vandalism - caving in the back of a car with my boot. Shame the police weren't there 2 mins earlier when the psycho cnut was trying to run me over
2 - Having something about my person I wasn't supposed to have
Then there's cops carrying me to a cell as a youth to sleep it off - but that's not an arrest, more like guardian angels.
Funny thing - I once had to go to the cops to show my driving documents. Like a dick, I managed to lock my keys in my car outside the cop-shop. I managed to get hold of a coat hanged and as I'm no whizz car thief, it took me 20 mins to break into the car. No-one batted an eyelid.

Got arrested for Embezzlement. Trumped up charge. Prosecutor saw the light and dropped the case - and got a new sofa in her office.
