This is from Jim E. “Jimmy” Snibbler [me@my.forest] on alt.humor.puns.

I think that my Mexican surfing friend takes a special, high energy food when surfing. They are kidney beans. They give him the tremendous, sustained energy that is required to breach an especially treacherous outcropping of coral near his favorite spot. I think he does this almost every day; he’s always raving about his mother’s reef ride beans.
