As seen on: The Big Bang Theory (CBS)
Portrayed by: Johnny Galecki
If you randomly watch an episode of The Big Bang Theory, chances are you will be flung into Leonard's sweaty, clingy nerd pessimissm about Penny—and that's not even the most annoying thing about him. No, his insufferable character trait that seals his fuck-out-of-here deal is how he pussy-foots around best friend/ roommate/psychotic brainiac Sheldon.
Yes, Leonard is the show's straight-man, but even Bud Abbott put Lou Costello in his place on occassion. Whenever Leonard concedes the left-side couch cushion to Sheldon, it's impossible not to want to slap the four-eyed nancy around out of frustration. Man up, son.
