20. Walter Bishop, "Fringe"
If there's another television show featuring a mad scientist who achieves impossible feats of fringe-science lunacy while snacking on double-dipped beer-battered onion rings from Sully's in his Harvard laboratory (where the awesomely named Gene the cow lives), I'm not watching it. And frankly, I don't want to. Walter Bishop is the best man of science on TV since Jack Shephard, and I'm not just saying that because he reminds me way too much of my own weird dad. (Though, seriously, the similarities are eerie and I'm beginning to wonder whether I'm from a parallel universe. That's neither here nor there.) Walter is hilarious, heartbreaking and horrific all in one stroke, thanks to the unparalleled genius of John Noble and the "Fringe" writing staff, and the fact that Dr. Bishop isn't an Emmy-winning character is absolutely beyond me — but hey, he's solved weirder problems in the past. Give the man some time. - Josh Wigler
