Mike, I absolutely love your show. Why? I can relate. I have done a lot of the jobs I have seen in your show, not all of them - but a lot.
I used to work in construction and I have cleaned out clogged plumbing with an auger, been in sanitary sewers for the purposes of inspection and been on my back in crawl spaces doing insulation (Personally, I'd rather be in a sanitary sewer then being on my back doing insulation, its just nasty). Not to mention gutting houses (and getting attacked by wasps in the process), digging holes, hot tar roofing and tearing off shingled roofs. I have since moved on to other things but seeing you do the above mentioned jobs brings it all back and I can't help but laugh and remember coming home completely and totally exhausted as I have seen you in some episodes.
I have to say though, you have the perfect personality for this show. Your not afraid to get right into it get your hands (and the rest of you) dirty. Please keep up the level of excellence that is Dirty Jobs because for me, it has become the measuring stick by which other shows are judged.
One of these days if your ever in Jersey again look me up so I can buy you a beer, you have definitely earned it.
