Two dwarfs go into a bar, where they pick up two prostitutes and take them to their separate hotel rooms.
The first dwarf, however, is unable to perform. His depression is enhanced by the fact that, from the next room, he hears cries of, "ONE, TWO, THREE...UUUUH!" all night long.
In the morning, the second dwarf asks the first, "How did it go?"
The first whispered back, "It was so embarrassing. I just couldn't perform. Things just wouldn't work."
The second dwarf shook his head.
"You think that's embarrassing?!!" he asked.
