I like the Stick it in the lake one!!!
I use the drink some water one, and the walk it off one myself, so long as it isn't too serious of course! I had a camper last weekend who swore she sprained her ankle when doing 3-legged races, but she wasn't crying at all (3rd grader or so) and still took off the bandana jsut fine. Then she got up and ran over to the next activity and told the person there that her ankle was sprained!! Too bad for her Spork had seen her run over!! haha
