Tonight on Dirty Jobs, Mike Rowe gets on all four and learns how to act like a cow. He learns everything he can about the cow’s bladder as the bladders will be used in the Mardi Gras festivities. The bladders go on floats to keep evil spirits away.

After seeing those four clips, I’d have to say it’s a pretty unusual thing to do with an animal organ, but I suppose it’s just as well we use as much of the animal as we can.

Tune in to Discovery Channel tonight at 9pm EST to catch Mike Rowe banging on some cow bladders.
