Input: Text: this morning as i was heading into work, i was stuck behind a dark grey dodge charger. after spending ten minutes behind the slow ass, (it was a two lane road), i saw a break of oncoming traffic so i gunned it around the slow poke, flipping him the bird as i did so. 

turns out the slow poke was an unmarked police car. one would think i would have gotten some kind of ticket. i got something else back instead. he shot me a bird of his own. 

i'd like to have a beer with that cop.

TIFU by flipping the bird to an undercover cop.
