NFL Football would be my favorite and most watched. I don't miss any Philadelphia Eagles games!
NHL Hockey is probably my 2nd favorite but I don't watch regularly or follow it unless we're having a really good season and approaching the playoffs.
Baseball, Nascar, and WWE wrestling are all in third place because I occasionally watch them but not on a regular basis. The last season of baseball I really watched was when the Phillies won the World Series in 2008.
I used to be into NBA basketball in the 90s and early 2000s but in recent years I've completely lost interest.
I'm not sure if it counts but I also enjoy watching the Olympics, particularly the summer over the winter, but not every single event.
Volleyball, Football, Soccer, Poker (if that counts), Poke her (you bet that counts :lol
