Laugh a little
Moishe, an elderly man, goes to a brothel and tells the madam that he would like a beautiful, young lady for the night. The madam gives him a quick look-over and is rather puzzled. So she asks him, "How old are you?"
"Why," replies Moishe, "I'm 98 years old today."
"Ninety-eight!" the madam exclaims. "Don't you realize you've had it?"
"Oh," he says, "in that case, how much do I owe you?"
