EDIT:
WOAHHH!! Ok, it's much bigger than I thought. I shrank it, the pic is now a link to the bigger version. Don't want my crap art to also be obnoxiously big.
This needs an explanation.
I used the episode of Big Bang Theory I was currently on as inspiration. The title was "The Tangerine Factor." I drew and shaded/highlighted the whole picture and when it came to putting the words, "The Tangerine Factor" didn't quite work. But I was listening to The Hush Sound's "Sweet Tangerine." Awesome coincidence? Yes.
That's why I have a picture of a girl doing math with breakup lyrics in the background.
Whatever, boys can yearn for nerdy girls. Why not?
