Buying a shoe

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 the mans feet. - "Try pulling the tongue out." offers the clerk. - "Nath theyth sthill feelth a bith tighth." He says.
