I think this is tongue-in-cheek.
I could not stand my freshman roommate, but I am hard pressed to recall why he annoyed me so.
Hell, in high school, my roommate (a 225 lb lineman for the football team) was stinky, but he protected me (a 150 lb running back). We both stank...
You think he would have thought of something really funny, but I guess this reveals his sense of humor. Cruz is really funny.
