'Two and a Half Men' viewers went into a tizzy when Thomas Gibson and Jenna Elfman popped up as potential buyers of Charlie Harper's pad in the Season 9 premiere, seemingly reprising their 'Dharma & Greg' characters. But were they really playing Dharma and Greg?

"I don't think it really was Dharma and Greg," Gibson told AOL TV. "It was a Dharma and Greg-like couple perhaps."

So was it more of a wink at the audience than an actual reunion? Gibson explains the uncertainty: "Well, you see actually because 'Dharma & Greg' was a 20th Century Fox show for ABC and 'Two and a Half Men' is a Warner Bros. show for CBS."

For fans who were worrying Dharma and Greg were no longer a happily married couple, Gibson wants to put those fears to rest. If indeed that was the titular characters, they were just having a bad day.

"I don't think they hate each other, I think they were just having a bad day or maybe even a bad 10 minutes," he said. "They're still together, things could be just fine and they could just be having a very biorhythmically critical day."

So, there you have it, "faux-Dharma & Greg" are doing just fine.

"It was great, it was nice," Gibson said of reuniting with Elfman. "It was a great idea Chuck [Lorre] had and I thought, well, yeah that's actually really, really funny way of burying little secrets in the season opener of 'Two and a Half Men.'"
