Math lessons...

this is a quite old drawing (11-3-06), and I decided to submit it only yesterday, having fun remembering when I did it...I was at a university math lesson but no one was understanding what the hell the teacher was saying and so...I pulled out the sheet and made it spontaneously, it came out of my hand the way you see it...In fact as you can see I'm totally unable to draw and I think I've badly mistaken the left leg (like the rest but it's not so evident!!!!!!)
