An elderly couple sat through a porno movie twice. They didn't get up to leave until the theatre was ready to close for the night. "You folks must've enjoyed the show," the usher said. "Disgusting, " said the old lady. "It was revolting," her husband added.
"Then why did you sit through it twice?" the usher asks.
"We had to wait until you turned up the house lights," the old lady replied. "We couldn't find my panties, and his teeth were in them!"
