Oh yes, this is the greatest jerk-ish pleasure of mine too. I live in a small city in the UK, but it's a tourist-magnet so the footpath (or sidewalks if you're American) are always crammed with people. I love giving 'em the stiff shoulder, but the other day it back-fired. A group of teenage schlongs parted for these two guys in front of me but then came back together as a group, so when I went through them I pinballed from one girl to this douchey guy, who proceeded to yell "what the fuck?!" at ME! What could I have done?? They crowded around me! God, people on the street... I just want to scratch their eyes out with my keys.
