One reason (of many, probably) I am a huge pain in the ass to watch tv with:
I will obsess, out loud and through multiple episodes, about remembering the name of the artist whose paintings are in the background of the "House" set. (I can't find any great screenshots of this so you know what I'm rambling on about, but if you watch as obsessively as I do, it's the first-floor lobby very near the elevator.)
"Dammit, I know he had a big exhibition here in 2007. And one of his squares paintings was on all the membership info for the Contemporary Arts Center for that whole season. Why can't I remember his name?!?"
And then, four hours later, I will track you down and yell "JULIAN STANCZAK!" without any context at all.
