At last night’s Alzheimer’s Association Benefit in Beverly Hills, the entire cast of The Big Bang Theory took the stage to perform numbers from Grease for a good cause.

But the moment that’s got the Internet talking today is Kaley’s solo performance of "Dance: Ten; Looks: Three" from A Chorus Line – a song that fans may remember for lyrics that frequently repeat the phrase "t-ts and ass."

As you can see, Kaley got pretty into her performance, even pointing out the name-checked body parts as she belted out the tune.

Needless to say, the crowd on hand was entertained, and millions more are enjoying video of the performance today.

We’re not surprised that Kaley left it all on the stage. After all, we’ve seen her writhe around while doing her best Britney Spears impression on Lip Sync Battle

The girl might be best known for her TV work, but clearly she’s got a knack for making her presence known on stage as well.

Based on this clip, we’re gonna go ahead and assume that there’s not truth to the rumors of Kaley being fired from The Big Bang Theory.

Not only was she friendly with the rest of the cast all night, but even the most cold-hearted exec couldn’t can her after that performance.
