Two dwarfs decide to treat themselves to a vacation in Las Vegas. At the hotel bar, they're dazzled by two women, and wind up taking them to their separate rooms.

The first dwarf is disappointed, however, as he's unable to achieve an erection. His depression is enhanced by the fact that, from the next room, he hears cries of ONE, TWO, THREE... I'M COMING AHHHHHH! all night long.

In the morning, the second dwarf asks the first, How did it go? The first whispers back: It was so embarrassing. I simply couldn't get an erection. The second dwarf shook his head. You think that's embarrassing? I couldn't even get on the bed!
