I wonder if Sheldon ever wakes up and thinks to himself:
"Hmm... maybe today I won't be totally magical... maybe today I won't be a huge ray of sunshine for anyone that has ever thought fondly of a bike... maybe today I will just try not to be the apple of everyone on here's collective eye... hmm... maybe I'll just stay in bed and not do anything"

and then he stays in bed, and he is still totally all those things. It's so comforting to know that there's a Sheldon in the world. Like, yeah, the world sucks and I'm angry a lot of the time... But, my gosh, that picture pretty much could make the frowning of a whole century dissappear. No joke.
