Big Bang Theory Quote
Sheldon: FYI, my noise-cancelling headphones proved ineffective last night.
Penny: Yeah, sorry about that.
Sheldon: As a native Texan, I must say I've never heard the phrase 'yeeehaw' used in quite that context.
Penny: Oh God!
(she leaves)
Sheldon: Oh, God. That I've heard on multiple occasions.
