Four farmers were seated at the bar in a tavern. At the table next to them sat a young girl.
The first man said, "I think it's WOOMB." The second replied, "No, it must be WOOOOMBH." The third said, "You both have it wrong -- it's WOOM." The fourth stated, "No, it has to be WOOMMMMBBB."
At this, the young lady could stand it no longer. She got up, walked over to the farmers and said, "Look, you hayseeds, it's WOMB. That's it, that's all there is to it." Then she left.
Eventually, one of the farmers broke the silence by saying, "Well, I don't know. A slip of a girl like that, I don't see how she could know. I'll bet she's never even heard an elephant fart!"
