Maybe because the letters are all clumpy and there's no pee stream connecting them. But considering that he is a robot he would have excellent bladder control and could stop the stream anytime he wanted. I'm going for the rorshach test explanation. This guy needs to see his doctor cause he's dribbling a lot.
It looks like he's going pee pee. You know like writing your name with piss kind of thing. I could never get very far as Michael but when I switched to Mike as a 10 year old, things got better for me, I could usually make it almost to E. Now that I'm Michael again and getting a little older I'm worse off than before.
This little faceless Michelin man has a lot of piss, he is so talented with his weiner that he doesn't even have to hold it to write out the names of bands. Either that or he is raising his hand because it's a pissing contest and he is the first one done.
