What kind of Winter Bar League would you be in?!

I am in charge of coming up with various leagues that patrons can participate in at the bar. Over the summer we do a Bags League but now that its getting colder we can't do that anymore. We are looking for something on a Sunday afternoon. Also, we already have a Euchre night that runs year round. Any suggestions of things we can do? If it helps we do not have a pool table or dart board.
