16 APRIL 2014
I'm actually a few days late on this; my apologies. Blame the Blood Moon and the IRS.
Honoring their generous tradition of contests, the Big Bang Theory wants to send you to Comic-Con. And like so many contests this year, it's of limited duration. All the better for other people to miss it, I say.
When: NOW. This contest runs every day from 14-25 April.
How: Watch the show, then click the correct word of the day on the site to enter. There are other prizes, but the grand prize is a full trip to San Diego Comic-Con.
