All this talk about pranks on the hipster bike got me thinking. What are the best bike pranks? Preferably pranks that don't end in major injuries. Here's my favorite one to start: Pump your friends tires with water- the weight is just out of control and it makes your bike handle SO bad. The only time I've tried it, I had to fill a bucket with water, suck water into a floor pump, then start filling. The girl I did it to (I know, I'm terrible) commuted for a solid month before figuring out what was wrong. And no, she wasn't a hipster PS- the one about cutting the bars a little each day is hilarious!
