When Danza heard that Al occasionally taught his math class because he was so good at it, Danza decided to get a point across to him. Al often came in late to Danza's class, yawned loudly and asked off-topic questions. When Danza went to sit in on Al teaching, he wore a backpack like Al's, a sweatshirt and sneakers like Al's. "I take a student seat and put my feet up on a nearby desk," he wrote. "I loudly unwrap a sandwich, which I proceed to eat as he watches from the teacher's spot and tries to do his job... when he calls on me, I ask a question about bacon, which for some reason he's always talking about. He ignores me the same way I do him when he asks dumb questions... I ask him, 'What do you think about teaching now? Not that easy, right?' He won't admit it, but his face softens."
