two red indians and an irishman are walking through the woods. all of a sudden one of the red indians runs up a hill to the mouth of a small cave. he calls "wooooo! wooooo! wooooo!" into the cave and listens closely. a voice answers back "wooooo! wooooo! wooooo!" and he tears off his clothes and runs into the cave.
the irishman was puzzled and says to the remaining indian "is he crazy or what?". the indian replies "no, it is our custom during mating season when indian man see cave, they holler 'wooooo! wooooo! wooooo!' into the opening. if they get an answer back, it means theres a beautiful squaw in there waiting for him".
soon after they come upon another cave. the second indian runs up to the cave, stops and hollers "wooooo! wooooo! wooooo!". immediately, there was the answer "wooooo! wooooo! wooooo!" from deep inside. so he tears off his clothes and runs into the opening.
the irishman wanders around in the woods alone for a while when he spies a third large cave. he looks in amazement at the size of the huge opening and thinks 'oh man, look at the size of this cave! it is bigger than those the indians found. there must be a really fine woman in this cave!'
so he stands in front of the opening and hollers with all his might "wooooo! wooooo! wooooo!". he then hears an answering "wooooooooo, wooooooooo, wooooooooo!". with a gleam in his eye and a smile on his face, he races into the cave, tearing off his clothes as he ran.
the following day, the headline of the local newspaper read 'naked irishman run over by train'!
