Hmmm..... let's see. I deposited empty check envelopes into my bank's ATM machine. Got away with it once, they weren't too happy the second time. Needless to say I had to find a new bank.
Also, one time I decided to leave my ATM card at work, that way I wouldn't be able to drink in the evening. So of course after counting my change and getting 5 or 6 beers in me, I thought it would be a great idea at 2 in the morning to scale the gate of my work and try to break into my office. Luckily I wasn't successful or caught.
I've said it before and I'll say it again, I am EXTREMELY lucky that I have no criminal record.
