Activities. Sign each others shirts with Sharpies and write a short message to the other on the back that you can only look at after you take it off. Play catch with a nurf football. Sing the fight song with gusto after touchdowns! Take a drink after every BYU first down and first one that has to pee has to kiss a nurse! Tell each other your favorite BYU memories during commercials. Make a list of his top/favorite players and favorite games.

At least...that's what I would do.
