Last night I was riding with a friend after work. We were pushing hard on the last stretch and something caught my eye in the roadway: A $5 bill. I yelled at him to stop and I jumped off my bike and ran back and picked it up. I felt kind of bad because I couldn't share my new-found wealth with him, but as providence would have it, another car drove by and another $5 bill was kicked up from the roadway and floated over to my feet. I bought ice cream with it.
