Watch it

“Saturday Night Live” (11:30 p.m., NBC). Jon Hamm of “Mad Men” hosts. But Michael Buble is musical guests.  In terms of coolness, they kinda cancel each other out. You might be surprised by Hamm though, he’s funny.

Skip it

Everything else. Wow, there’s absolutely nothing on tonight. Go watch a movie.

Games of the day

College basketball: Duke at Georgetown (10 a.m., CBS). It’s the Blue Devils’ great backcourt vs. the Hoyas’ tough frontcourt. Should be a good game. And it’s never too early in the day to boo Duke.

Soccer: Argentina vs. Costa Rica (1 p.m., Telemundo). Hey, why not? It’s never too early to catch World Cup fever.

Winter X Games (1 p.m., ESPN2 and 6 p.m., ESPN). It’s usually kinda stupid, but snowboarding and skiing are fun to watch.

College football: Senior Bowl (1 p.m., NFL). Watch Tim Tebow’s stock fall in the NFL Draft. There’s actually no reason in the world to watch this unless you’re an off-the-charts insane football fan.

Tennis: Australian Open women’s final (7 p.m., ESPN2). Venus Williams takes on Justine Henin, who’s playing in only her second tournament since her nearly-two-year “retirement.”
