Do you ever find yourself talking to someone, and they say something pretty vague, but you know a certain song includes it...then you start singing the song? For example, your friend says, "I'm going out tonight," and you start singing, "I'm feeling alright...gonna let it all hang out...wanna make some noise...really raise my voice...yeah, I wanna, scream and shout." (Shania, in case you needed the hint).
It happens to me in almost every single conversation I have with someone. It's a problem. At least I've found a way to not physically sing the song, and I keep it to myself. But then, I feel like I want to sing it to see if they realized that they're spitting lyrics. Anyways - long story short: I'd be best friends with Justin Timberlake and Jimmy Fallon.
