So, how Dirty Jobs host Mike Rowe get this gig? "I was hosting Evening Magazine in San Francisco, and pitched a segment called Somebody's Gotta Do It. We started to profile unusual jobs in the Bay Area, and before long, I found myself extracting the semen from a prize bull and placing it (very gently) into the uterus of a cow. That segment got a lot of attention, and we discovered there were tons of other exciting and dirty jobs out there.

"That's when we pitched the idea to Discovery Channel and thus launched the Dirty Jobs series."
