I used to have a lot of horrible jokes I used to tell people when I was a raft guide, before I got fired for smoking up. Here's a couple I can remember.

What do you call a fish with no eyes?
-Fsh

Why can't Barbie get pregnant?
-Because Ken comes in a different box.

What did the lifeguard say to the drowning hippie?
-"You're too far out man!"
