Michelangelo's behavior.

It seems to me that Michelangelo is one of the most inconsiderate members of the TMNT team, in fact I'd say he is the most inconsiderate member of the team....... He took advantage of Raphael's fear of the Cockroach Terminator to try and get Raphael to let him read his comics once in a while, and he even got pizza grease on Raphael's comics, which is hugely disrespectful. And he pulls pranks without any regard for the feelings of others.
