Back at University, I used to play football with the other guys regularly. I sketched one of the funniest moments; one of my friends was playing with his top off. When he scored a hat trick, he celebrated by going fully naked, apparently something he did quite a lot anyway.
In real life his junk was kind of flopping around a lot, but I chose not to draw that; imagine its hidden by his legs.
I don't get to play football quite so much these days.
