Sticker #347I'm Passing Gas!

A classy, subtle statement, suitable for all occasions. But specifically, this one is suitable for the sort of occasion where you are riding you bicycle past a gas station. Or the sort of occasion where you choose to ride your bike instead of sit in a car. Or the sort of occasion where you ride your bicycle faster than the cars. Or maybe it's just for the sort of occasion where you ate too many lentils and can't stop farting (while riding your bicycle, of course)!

(Sturdy vinyl sticker with black print on a white background. Reads: "I'm passing gas" with a gas pump icon depicted on the left, and a bicycle icon depicted on the right)
