Would this by while I was sat on the chair or about to sit on it? I voted yes, if I was sat on it the chair wouldn't move and Moz would just end up hurting his foot so that would seem like a silly thing to do.
Alternatively if I was stood up/about to sit on it and he kicked the chair away and I went to sit down and fell on the floor I would get hurt and people would find that funny and I like making people laugh so yes in both cases.
