Horrible Hyena Humor

When a hyena is making its signature laughing sound it's expressing frustration, usually when fighting a more dominant hyena or other hyenas for food.

That bit of trivia reminds me of an old joke:

An old man took his grandson to the zoo and during the tour they stopped in front of the hyena cage. The tour guide said:

"This is the laughing hyena, so called because of its distinctive bark which sounds like laughter. It eats 45 lbs. of meat a week and only evacuates once a month."

The old man snorted and dryly said: "Hmmph! If that S.O.B. eats 45 lbs. of meat a week and only craps once a month, I don't see what the hell it's laughing about!"
