Waterproof boots

Last night we met a couple who had been to Antarctica about ten years ago. They said we'll love the trip. Then they said,"It's real important to have the high boots." I said, "I know, we'll be getting off into ice-cold water."

"Oh, no ... the boots are for the penguins!" Oops. Apparently, you can hear and smell the penguins before you can see them, if you are coming around an iceberg. So ... the boots are not just for the water, they are for getting through penguin poop.
