After spending a night at a hotel with a prostitute, the politician took
$300 out of his wallet and placed it on the dressing table.
"Thanks," she said. "But I only charge $20."
"Twenty bucks for the entire night?" the amazed MP replied. "You can't
make a living on that."
"Oh, don't worry," the whore replied. "I do a little blackmail on the 
side!"
