This...could be a problem

This picture stemmed off of a daydream I had during class once. I was staring out of the corner of my eye at the guy next to me and the girl on the other side of him. I daydreamed this big long story that was way too stupid far a story, but obviously not to stupid for a quick sketch. Well. The 'quick sketch' evolved into this drawing. Enjoy.

I drew this on blue lined notebook paper and spent a whole lot of time erasing the blue notepaper lines. Sorry if it looks blurry around some places. (If you know a better way to erase the lines other than attacking the drawing with my eraser and clone brush, please tell me!)
