Reading "Sirius" instead of "serious" is the key to that joke. The guy Harry's talking to is Remus Lupin, who teaches Defense against the Dark Arts in the third movie (and who is a werewolf), and who was one of his father's friends in school. Sirius being another such friend.
You should check out the other two movies, they're a lot of fun and less kids movie-ish than the first two.
