My old car was an automatic that at the time was in need of a new carb. (it wasn't ricey, just setting it up for my ricey mentality)

Anyways, I had a friend riding shotgun and a bunch of people (some friends included) were hanging outside. The friend talked me into doing a burnout. I did and then right when I started moving forward I let off the gas. My finicky carburetor didn't like this so my car immediately stalled. At which point I wanted to restart my car and quickly get out of there, so without thinking I slammed it back into park...while still rolling forward. Clunk clunk clunk. Then I cranked it back up and drove off.

The car was completely fine, and I actually didn't hear anything about it later, but damn I felt like a dumbass/douche bag.
