The guy Sheldon accidentally propositions is actually his IRL boyfriend. I could barely contain my glee.
This show has some really awesome moments- I just wish they were a little more frequent.
Raj: How about you decide this with Rock-Paper-Scissors-Lizard-Spock?
Kripke: What the frig is that?
Sheldon: Rock-Paper-Scissors-Lizard-Spock was created by Internet pioneer Sam Kass as an improvement on the classic game Rock-Paper-Scissors.
Penny: She’s upset, you’re her boyfriend; you have to at least try to be excited by the things she’s excited by.
Sheldon: What if they simply don’t excite me?
Penny: Well just… smile and think about koalas.
