“Broken Scale”
A goober holding a baby walks into a drug store and asks the clerk if she can use the store’s baby scale.
“Sorry, ma’am,” says the clerk. “Our baby scale is broken. But we can figure the baby’s weight if we weigh mother and baby together on the adult scale, and then weigh the mother alone, and subtract the second number from the first.”
“Oh, that won’t work,” says the goober.
“Why not?” asks the clerk.
“Because,” she answers, “I’m not the mother - I’m the aunt.”
I am off to see the Dr., back later.
