Hobo sitting on bench: Hey man, wanna buy some soap?
Yuppie: Nah… (walks away)
Hobo: Ma’am, would you care for some shoes?
JAP: Hell, naw. (walks away)
Hobo: Hey fella, want to buy some peanut butter?
Old Asian guy, happily: Yes, please!
Hobo: I’m sorry, brother, I don’t have any on me. I just wanted to do some product research for a project I’m doing. (pulls out a roll of toilet paper and a sharpie, rips out one square of toilet paper, and writes “peanut butter”)
