A PT Cruiser (in Philly's Old City of course) with five girls all yelled at the same time to a friend and I: "Get a car, losers!!" It was amazing. I always find that funny, because if you're living in Philadelphia, the losers are the people with cars. I should have yelled "Get a bike, losers!!" I tried to think of the most childish insult that would apply to them (25 year olds), so I yelled, "I'm in shape and you're ugly!! Get on the bike!!" And my friend reached into the car while it was moving next to us and pulled the girl's hair.
...yeah.
