DH would watch sports all day if I let him!
We watch - nearly all televised CFL games (and he records some to re-watch later).
We watch - curling - especially the Scotties Tournament of Hearts and the Briar as well as the international events
We watch some tennis - he would watch all of it, I limit it to the finals.
We watch hockey - but I try to limit it to 1 game a week or at least our hometeam.
He watches 4 or 5 NFL games each week (I drew the line in the off season and said that he was not allowed to watch repeat games).
He would watch more hockey and football for sure.
He watches some of the World Series, but otherwise not much baseball!
I would watch the Indy Car and F-1 races, but they are so long. So I sometimes just catch the end.
Wow, it sounds like we do nothing but watch sports - not true! I spend loads of time on JM too!
