Warner Bros. and CBS Consumer Products have teamed up to launch an exclusive, limited edition line of The Big Bang Theory/Star Trek merchandise which includes t-shirts and Funko bobbleheads featuring the guys in Starfleet uniforms. The new merchandise will be available only at Hot Topic stores nationwide and HotTopic.com from now until July. Hot Topic will also exclusively stock a new, limited edition The Big Bang Theory/DC Comics t-shirt featuring the guys in their favorite DC Comics costumes.

To support the new line of merchandise, Warner Bros. has teamed up with Hot Topic to run the second annual Ultimate Fan Giveaway offering an opportunity to attend the legendary Comic-Con International in San Diego.

From May 20 through May 31, fans can enter the contest by watching The Big Bang Theory every weeknight in syndication (selected markets only) and identifying Sheldon's special Hot Topic t-shirt online at BigBangContest.com, or by visiting any Hot Topic store nationwide by Sunday, signing up to be an HT+1 rewards member and purchasing any Big Bang Theory t-shirt. Find your local Big Bang Theory listings at BigBangWeeknights.com.

One lucky fan will receive an all-expenses paid trip for two to Comic-Con in San Diego, CA, including two tickets to Comic-Con, round-trip airfare, three days/two nights hotel accommodation, ground transportation and special access to various events at the Warner Bros. booth. In addition to the main prize, Warner Bros. Domestic Television Distribution is offering viewers in 17 select markets the chance to also win local prize packages that include $500 gift cards from Hot Topic.
