A blonde lady 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 woman.
"Why not?" asks the clerk.
"Because," she answers, "I'm not the mother - I'm the aunt."
