I've been making this list over the past four months or so. Far more of these apply to me than I care to mention.
Oh, and one more thing. I understand that a few are opinion based and that my opinion may differ from others'.
You know you are obsessed and consumed by The Big Bang Theory when…
You play “Rock-Paper-Scissors-Lizard-Spock” to resolve disputes.
You do three knock cadences when summoning someone.
You know all the words to “Soft Kitty.”
You have sung the aforementioned song as a round.
You shout “We built the pyramids!” during the theme song.
You know that Tweedy Bird really “taht he taw a Romulen.”
Your comeback to bullying is “a homo habilis discovering its opposable thumbs says what?”
You label everything in the house, including the label maker.
I seriously want to nominate him for best character on tv. :) At first he drove me crazy, but now i anxiously wait to see what kind of "over-our-heads" braniac thing he will say. He kinda reminds me of a robot from some sci-fi space odyssey that's been sent down to earth to live amongst the dumb humans. He really stands on the fine line of being a genius or being completely insane. Sometimes i can't tell. :) On the last episode when Penny put the alcohol in his diet coke, i thought i was gonna die cuz i was laughing soooo hard. Seeing him playing that piano and singing was priceless. Anyone else like Sheldon as much as me??? I look forward to next week's episode just to hear sheldon speak. Haha.
