I used to watch the show every week back in the day. But let's be honest. Going up against bad guys with guns (sometimes automatic) with his contraptions, traps, explosions, diversions, etc. would've simply got him shot in real life.
I get it that he didn't like guns, but why bring a knife to a gunfight....
Still a great show (to me, anyway) and I have quite a few episodes on DVR - and more being recorded each week.
