More ideas

One person on the Mike Rowe Fans group on Ravelry suggested the Happy Poo pattern. There was a lot of caca in the first season of Dirty Jobs, wasn't there?

I think I might try to knit him some safety goggles. Poor Mike gets yuck in his face and eyes a lot, doesn't he? Not sure where to start designing something like that, but I like a challenge. ;)

In case you are in need of more inspiration, here is a List of Dirty Jobs Episodes from Wikipedia.

Dirty Dishcloths

I'm wasting some valuable kids-watching-tv time by searching out dishcloth patterns that resemble some of the many jobs that Mike has performed on the show:
Construction Worker cloth
Shark cloth
Monkey cloth

I"m sure there are more, but those are the first few that struck me as topical. Plese feel free to put additional ideas in the comments section, and I'll add them as we go along. :)

And now, I leave you with this LOLMike from a photoshop challenge thread at Fark.com . That thread contains many photoshopped images of Mike Rowe in various spurious dirty jobs, some of them icky (not to mention NSFW). So click at your own risk.
