And then there are Garrison Kiellor's favourite jokes:

Two penguins are standing on an ice floe.
One turns to the other and says, "You look just like you're wearing a tuxedo."
The other one says, "How do you know I'm not?"

A grasshopper walks into a bar.
The bartender says, "You know, we have a drink named after you."
The grasshopper says, "Why would anybody name a drink Bob?"
