So great! It reminds me of an old joke:
Two carpenters are putting siding on a house. One notices the other picking nails out of his pouch, sometimes using the selected nail, sometimes tossing it over his shoulder.
“Why are you throwing those nails away?” he asks his mate.
“Because the heads are on the wrong end,” says his friend.
“You idiot! We could have used those on the other side of the house!”
