A drunk advised the clerk that he wanted to by a bra for his wife.

Clerk "Here are several styles to choose from, sir."
Drunk "This one will do the job!"
Clerk "Do you know the size that your wife requires,sir?"
Drunk "71/2"
Clerk "I'm sorry, sir, but bras are not made in that size. Here is standard listing of sizes. Perhaps you can pick from those."
Drunk "71/2"
Clerk "There is some mistake. Let me bring in our buyer to help."
Drunk "Measured it myself! Size is 71/2!!"
Clerk "But, sir--"
Drunk "71/2, God dammit!!!"
Clerk "Perhaps you can tell me how you measured? What did you use?
Drunk "My hat!"
