Many years back I thought it would be cool to make a pad of bills. I went to the bank and bought 100 one-dollar bills in sequential order. Then I used that office supply stuff and made a pad like a notepad. It was the funniest thing to go into 7-11 and buy something, then count off and tear off the bills. The dude behind the counter usually gazed in unbelief (of course, I did put a cover on it that said FUNNY MONEY PAD.)
In the post 9-11 world you would be shot for such a heinous display of terroristic tendencies. Don't try that trick in Baltimore!
