Dwarfs

Two dwarfs go into a bar, where they pick up two prostitutes and take them to their separate hotel rooms.

The first dwarf, however, can't get a hard on. His depression is made worse by the fact that, from the next room, he hears his little friend shouting out cries of "Here I come again...ONE, TWO,THREE...UUH!" all night long.

In the morning, the second dwarf asks the first, "How did it go?" The first mutters, "It was so embarrassing. I simply couldn't get a stiffy."

The second dwarf shook his head. "You think that's embarrassing? I couldn't even get on the bed."
