The Big Bang Theory Theme Song

Kaley Cuoco appeared on Jimmy Fallon this week and shocked the audience by singing the entirety of The Big Bang Theory theme song.

The Big Bang Theory theme song is iconic. It was written by The Barenaked Ladies after Chuck Lorre attended one of their concerts where lead singer Steven Page did improv about “The History Of The World.” Chuck knew that he had to have these guys record the song, and the rest is history.

After ten seasons on the show, it seems Kaley Cuoco has had enough time to practice this famous tune. On the Jimmy Fallon show, she revealed that she and Johnny Galecki frequently speak to their live audience in between takes. They take questions and have fun with fans. Jimmy loved the idea and wanted to try it out on his studio audience.

The final question was for Kaley. A fan wanted to know if she knew all of the words to the theme song. Kaley was ready to prove she could sing the whole thing. Jimmy’s band The Roots helped her out, and she successfully finished the thirty-second jingle to perfection.

In case you forgot the lyrics:

Our whole universe was in a hot, dense state,
Then nearly fourteen billion years ago expansion started. Wait…
The Earth began to cool,
The autotrophs began to drool,
Neanderthals developed tools,
We built a wall (we built the pyramids),
Math, science, history, unraveling the mystery,
That all started with the big bang (bang)!

There was a whole other minute to the song, but Chuck Lorre and others decided to condense it further to make it easier to listen to over and over again. This approach worked- The Big Bang Theory theme song has now been airing on television for ten years, and has two more seasons (AT LEAST) to go.

Are your surprised Kaley Cuoco knows all of the lyrics to The Big Bang Theory theme song?
