Leonard: We think we can help you with your stage fright.
Sheldon: Oh, I doubt that. I haven't figured out a way, and I'm much smarter than all of you.
Penny: Yes, but you're not smarter than all of us put together.
Sheldon: Oh, I'm sorry, that is what I meant.

"Sherman J. Hamster is a genius, and with all that genius comes a great big honkin' ego. His heart's in the right place, but it only stands to reason he'll need to show off his brain once in a while. I mean, it's like having a new car, and you've just got to show it off to your friends because you know thleat they don't have this car."

"In any standard crime show, only one character can be a sci-fi geek, and it's usually the scientist or lab technician in the group. So what do you do when your entire cast is made up of lab technicians? How do you choose?!? Apparently, you make your geek the lab tech who's more pompous and annoying than all of the other lab techs put together. Sure, let's make the smug, superior guy the Star Trek—sorry, "Astro Quest" fan. Clearly, THIS is the guy who would go to conventions in costume, fantasize about his co-workers in Astro Quest-themed scenarios, refer to himself as a "padawan" and name his cat "Kobayashi Maru." Not the hunky lab tech with the smoldering eyes—the dillweed. Stop giving Astro Quest fans a bad name, Hodges!"
