'Big Bang Theory' Cast Celebrates 100th Episode


The Big Bang Theory reaches a milestone Thursday with the broadcast of its hundredth episode, and as the cast and crew gathered last month to celebrate the achievement, they dished a spoiler or two to ET regarding the much-anticipated show.

A 'Big Bang Theory' Wedding?

"The hundredth episode is very quirky," reveals cast member Mayim Bialik. "It's a little bit outside of the normal format of what we normally do, and it's richly focused around Leonard and Penny. I think we're not done really seeing a lot of levels of that relationship and it's very funny."

In light of Penny's recent drunken confession of breakup regret to ex-flame Leonard, we wonder... do Mayim's words point to a romantic re-kindling for the pair in the near future?

"The 100th episode messes with your mind," teased Kaley Cuoco of the possibility. "It's like nothing we've ever done before."

TBBT's executive producer Chuck Lorre was a bit more forthcoming in matter, confirming to ET that there is "very much so" a "Penny/Leonard romance in the hundredth episode" to look forward to. "We decided to go back to where we started for the hundredth. I hope people like it."
