The Drew Carey Show
Malcolm in the Middle... ... ... No pun intended-- not trying to be pedo-ish. It's just a fucking funny show. The earlier seasons were the better ones, before everyone grew up.
(Dare I say?) MacGyver
As a child, the show inspired me to take everything apart--EVERYTHING (from radios, VCRs and remote controls to R/C cars and GI Joes and old broken electrical equipment that oddly enough started working again). I recently saw an episode and realized how shmaltzy the actual story was. At least the gizmos and devices were still interesting.
