in the second season who was funnier screech or bobby Wilson?

It was a really tough call (and it really was), but I honestly believe Bobby Wilson (Spankee Rodgers) was slightly more hilarious--and far less annoying--than Screech; in fact, Bobby was a hell of a lot more tolerable than his SBTB: The New Class "predecessor" (so to speak), bumbling and inept nerd Barton "Weasel" Wyzell (Isaac Lidsky). As talented as Spankee Rodgers was, it's too bad he (as well as Bobby) didn't survive past SBTB: The New Class' second season.
