Like NUCLEAR. So much so that he was yelling so loud and stomping around so much with his Eagles slippers (Christmas gift) that I kept yelling "HELP!" whenever he made me jump out of my seat while my sister and I played Sporcle on the couch. I feel bad for him because neither my sister nor I nor my mom care for football. Poor guy needs a kid who, you know, can revel in the ups and downs of being a sports fanatic with him.
Oh well. His team won, so he's the happiest person right now.
