Stupidity Just A Stone’s Throw Away

Customer: “Hi. I’m looking for the birthstone for May.”

Me: “Well, the birthstone for May is emerald, but we don’t carry any emeralds.”

(The customer walks over and looks in the case. She sees a green stone.)

Customer: “What about this green one?”

Me: “Oh! That’s peridot. That’s the birthstone for August.”

Customer: “Who’s August?”
