What? You’re familiar with onomatopoeias?
I swear this is how the 3rd knock sounds like every time!
Knock Knock Kncok…
Can you hear it?
Knock Knock Knock… Sheldon!
Knock Knock Knock… Sheldon!
Knock Knock Knock… Sheldon!
very nice, and nb4 people start fellating each other for liking that abortion of a show
Well! Excuse me for thinking I’d rather 69 with Berg than with you!
You must be a real-life engineer or physicist.
I’m a real life engineer and I thoroughly enjoy the show. He must not get the jokes. He must have lost all understanding on the rock-paper-scissor-lizard-Spock skit.
Kaley is for the win. She even looks good in waitress shoes (on the show).
No, I find the “comedy” lacking. It is rife with stereotypical sitcom pitfalls only tweaked to try to add “nerd” chic. They don’t even get all the nerd stuff right, factually or culturally. The laugh track is nauseating as well. It’s just a sitcom (the dried up form of sitcom) view of “nerds”, and I’m confounded as to why people who seemed otherwise intelligent would find this type of nerd pandering amusing.
i agree.
TROLOLOLOLOL

I read the description before I looked at the picture. I got it right away, which is weird because I didn’t think I knew anything about her.

Oh… no one ever gets it right…
Woohoo, this is the first one I guessed right! xD I’m so pro now.
Anyway, I think she’s one of the most beautiful actresses there are.
Lol came across this as I was watching Big Bang Theory
guys… you must remember the swimming pool scene in Growing Up Brady was shot when she was only 14!!! so hot, yet totally jail bait…
I recognized her right away without the hints.
What show besides Big Bang Theory is being referred to in the hints though? Someone mentioned Charmed, but that isn’t it, is it?
8 Simple Rules
Three very awesome shows (in my opinion).
I love 8 Simple Rules and Big Bang Theory
Did y’all know she played a young Ellen DeGeneres on Ellen’s sitcom?
She’s got a mad refund gap.
