Skim Milk

To help a friend lose weight, I told her that she should
switch to lower-fat foods, including skim milk. When she
said her family would drink only whole milk, I suggested
that she keep their regular container and refill it with
skim milk. This worked for quite a while, until her daughter
asked one morning whether the milk was okay.

“Sure, it’s fine,” my friend answered, fearing she had been
found out. “Why do you ask?”

The daughter explained, “Well, according to the expiration
date, this milk expired two years ago!”
