There are two penguins on an iceflow.

One says to the other,
“You look like you could be wearing a tuxedo”.

The other one says,
“How do you know that I’m not?”

This is an old favorite from Garrison Keillor’s A Prairie Home Companion.

If you’ve never heard the Prairie Home Companion (on NPR), I recommend you check out
