Who is the smartest Mythbuster?

Grant and Jamie are probably the two smartest, cause making robots is hard!

Grant. The man constructs robots.

I don't know about smartest, but Tory and Grant are my favorites. They really steal the show from Adam and Jamie.

Grant

I'd go with Jamie, i think that dude could build you a nuclear reactor if you asked.

I don't even know their names. 
 
All i know is there are Two Asians, one Italian dude......and other people. 
 
Or wait is that the wrong show? oh damn i think i'm thinking of another show on Discovery channel or something.

I'll say Grant. The dude built the modern version of R2D2, and he's bloody good with pneumatics. Great performances in Battlebots and Junkyard Wars is also a plus.

Grant, Jamie's up there as well, but he's such a tool.

Gotta go with Grant, although Jamie is a close second.  Adam is also no slouch, of course, but he's usually hampered by being goddamn ridiculous whenever he gets to do whatever he wants.

Grant is, Jamie is second, I don't even know why they others are on that show.
