He said a lot.
I thought Kimmel and Leno were friendly (at least in the past, going on each others shows during the strike and whatnot). That was pretty great.
EDIT: I'm not entirely sure what to think about it though. It's not like the show airs live, so if they were really worried about his comments they could have easily just cut them out. Either way, Kimmel made me laugh harder than he has in a long time (well, since his Leno show).
