The Big Bang Theory Connection You Never Noticed In The Flash

In addition to being a theoretical physicist, B.Sc., M.Sc., M.A., Ph.D. and Sc.D., Sheldon Cooper (Jim Parsons) is a geek fashion icon. He was wearing t-shirts featuring comic book characters long before the Avengers movies made them a staple in wardrobes around the world. While Captain America's shield or Superman's 'S' logo have become go-tos for many people looking to express their now-cool nerdy knowledge of superheroes, Sheldon digs a little deeper into the layers of superhero lore.

One of his favorite characters is The Flash. He has at least ten t-shirts paying tribute to the Fastest Man Alive, and dresses up as the character multiple times in the series. He even spends a whole episode pretending to be The Flash, complete with costume of course, and later has a dream in which The Flash (Brandon W. Jones) convinces him to try an energy drink.

There are lots of hidden things you missed in The Big Bang Theory. One of the things you never noticed in The Big Bang Theory's final episode even revolves around Sheldon's t-shirts. But Sheldon's love for The Flash didn't go unnoticed in TV world. This is the subtle connection between The Flash and The Big Bang Theory you likely missed.

Cisco Ramon pays tribute to Sheldon in The CW's The Flash

Another TV character with excellent taste in geeky graphic t-shirts is The Flash's Cisco Ramon (Carlos Valdes), a.k.a. Vibe. In recognition of Sheldon's sartorial tributes to The Flash, in the pilot episode of CW's series The Flash, Cisco dons a "Bazinga!" tee, honoring Sheldon's classic catchphrase. As MTV News reported, he's also worn a t-shirt with a picture of Sheldon's couch spot, a "rock, paper, scissors, lizard, Spock" t-shirt, and a t-shirt that Sheldon also owns.

We might have Valdes to thank for the crossover — he takes an active interest in his character's costumes. He told Showbiz Junkies that he and costume designer Kate Main work together to come up with Cisco's wardrobe. "We pull most of our shirts from Threadless.com and I basically look through them and I say, 'This is a shirt Cisco would wear.'" From there, Main has to see if they can get the rights.

The Big Bang Theory is over, but one of Sheldon's Flash t-shirts will live on for posterity. The night the finale aired, the cast announced on The Late Show with Stephen Colbert that Warner Bros. TV had donated several of the show's most famous costumes to the Smithsonian — including Sheldon's classic Flash logo t-shirt.
