Simpsons 30th Anniversary Couch Gag Parodies Big Bang Theory, Shows Famous Scenes

The opening couch gag for Sunday night's episode of The Simpsons
was a parody of the The Big Bang Theory. If you missed it or want to watch again, the video is now on YouTube. It's special in that it celebrates the 30th anniversary of the show's debut as a short that premiered on April 19, 1987 as part of the Tracey Ullman Show (via EW).

The gag riffs on the Barenaked Ladies song from The Big Bang Theory, as memorable scenes from across the animated show's 30-year run play. Mr. Plow, Bart (trying to) sell his soul, "alcohol and night swimming" are all represented, among other memorable moments. The new, Simpsons-styled lyrics are also a nice touch.

According to EW, there will be a "special surprise" about The Simpsons coming later tonight in the US. We'll report back with more details as they become available.

The Big Bang Theory airs on CBS, whose parent company--CBS Corp.--also owns GameSpot.
