A Double Mother What?

Sabrina just came home from camp. Here's what she learned:

1. What elephant seals look like close up.
2. How to fall down sand dunes.
3. How to fall in tide pools.
4. How to kiss a banana slug.
5. How to call people "super wieners."
5. A rap about animal poop, which she has graciously taught to the whole family.
6. A seal joke where the punch line was "Double mother-suckler."

Man, camp was never that good when I was a kid.
