"Hey, Joe, how did the pearl harvest go today."
"Nada boss, oh, but I found one skeleton. Real jerk that guy."
Note that the skeleton is basically stuck to the clam. He's been in there a while. There are no pearls, but there's certainly other presents left by the skeleton in desperate need of a bathroom. The fish in the bottom left? They are having nothing of it -- they might eat their own feces -- but they draw the line at soggy skeleton feces.
Another great band name!
