At the shoe store...

A man walks into a shoe store, and tries on a pair of shoes. "How do they feel?" asks the sales clerk.

"Well they feel a bit tight," replies the man.

The assistant promptly bends down and has a look at the shoes and at the man's feet. "Try pulling the tongue out," the clerk says.

"Well, theyth sthill feelth a bith tighth." (DOH!)
