"Santa Singh makes a bad deal !" joke

Santa goes to the local novelty shop and finds a pair
of x-ray glasses. He checks them out, but isn`t fully
convinced.
The store assistant comes along and closes the deal.
On his way home, Santa puts on his new x-ray glasses
and, bingo, he sees everyone in the street naked!
He takes them off for a moment,
and everyone has their clothes on.
Puts the glasses back on... everyone is naked! "Cool!"
As he arrives back home, he is eager to show his new
toy to his wife but can`t find her.
He goes up to the bedroom and finds his wife and some
guy, naked in bed.
He takes his glasses off, and the two are still naked.
He puts them back on, and they are still naked.
Santa gets disgusted and says, "Damn,
I just paid fifty-bucks for these,
and they`re already broken!"
