I found a ten pound brick labeled ” Expert SKIPPING STONE. its all in the wrist” by my computer.

Students are baffled by it. ( except for the one who gave it to me) They pick it up and say ” Its a BRICK! why would you buy a BRICK?”  Or  they say

“How can you skip this? It weighs ten pounds!”   Boys will pick it up and go off scratching their heads, muttering to themselves.

” What the …how ??”

It doesn’t immediately occur to anyone that this is a joke.
