Rugby Union - Horrible nasty worm of a sport which tried to choke the life out of Rugby League and still does do to some extent. (Pillaging RL in Russia for it's best players for their 7's team, getting the Vichy goverment to ban League during the second world war and not apologising for it, basically ostracising any player that went to League before the sport turn pro in 1995).
Horrible to watch as well, and the fans have the cheek to claim it's intelligent and thoughtful, it's neither it's boring.
I'll watch anything that's on really, but my favourites are:
Footy - watch and play, I'm a really good player, and by really good I mean piss poor at best. Got a season ticket at Everton.
Gridiron - It doesn't matter who's playing if there's an NCAA or NFL game on I'll watch it. Love the Denver Broncos.
Baseball - After spending 3 weeks in the States the only sport at the time to watch was the baseball, both football seasons had finished, so I started watching it and have watched it ever since. Don't really support any one team.
Formula One - Love it, hopefully will go to my first race next season. Hope Robert Kubica comes back soon.
Love football(Man united fan, soft spot for Villa and Chelski too) but I'll pretty much watch anything(Basketball, Rugby, Hockey, even American Football) if I'm in a good mood except for Golf, that just bores the crap out of me.
