A man proposes a one dollar bar bet to a well endowed young lady that despite her dress being buttoned to the neck, he can touch her breasts without touching her clothes.
Since this doesn't seem remotely possible, she is intrigued and accepts the bet. He steps up, cups his hands around her breasts and squeezes firmly.
With a baffled look, she says, "Hey, you touched my clothes."
"Okay, here's your dollar," he replies.
