Quotes (7)

Penny: No big deal. Not knowing is part of the fun!
Sheldon: 'Not knowing is part of the fun.' Was that the motto of your community college?

Rajesh: Why so glum, chum?
Sheldon: Apparently you can't hack into a government supercomputer and then try to buy uranium without the Department of Homeland Security tattling to your mother.

Sheldon: So, you're saying this is a regulation deck?
Howard: I'm saying believe in magic, you muggle.

Leonard: Okay, uh, how do I put this? Um, are you familiar with Darwin's observation of the finches in the Galapagos Islands?
Penny: Did they make a movie about it?
Leonard: No.
Penny: Then no.

Sheldon: If you plan on having children I suggest you switch from briefs to boxers, your testicles look a tad warm.

Howard fooled Sheldon with a magic trick

A writer and producer for BBT is Eddie Gorodestky, who at one time, 30 years ago was a writer for SCTV. In a book written by Dave Thomas about SCTV, Eddie was known for peering his head around the corner before entering a room. Dave also did an impression of him on SCTV in a sketch called Revenge, he uused part of his name in the sketch. I really don't like Raj's sister much, I find her to be a little cold. I kind of liked it when Sheldon got back at her. Even with Sheldon in his faults, I rather hang out with him than her.

People, please hv faith in Chuck Lorre. He's brought us this far - he's not gona let us down. For the record, I hate it when someone gets the better of Sheldon, but if he always had his way, it wouldn't be as much fun, now would it? It's funny when "non-geniuses" get the better of him once in a while.

I think with the addition of Priya (and sometimes Amy) the group dynamic of the original 5 has started to fizzle...especially if Leonard is no longer going to hang out with Penny. Whatever happened to Leonard not giving up on Penny like he promised her father!? I do like Bernadette though - she fit in well!
