Seems like the atmosphere got hot and steamy, when 'The Big Bang Theory' cast recently appeared in a talk show.
On the occasion of their 200th episode celebration, Mayim Bialik and Johnny Galecki were reminded of their first on-screen kiss with each other back in the 90s, News.com.au reported.

The 40-year-old actor said that it was the first stage kiss for both of them, to which Bialik added that the 1991 smooch was her first "real-life kiss, also."
Kunal Nayyar dared the pair to "do it again" and while they initially declined, it wasn't long before they were locking lips in a lengthy pash.
Sensing the mood in the room, Kaley Cuoco and Jim Parsons and Melissa Rauch and Kunal Nayyar also got in on the action, leaning in to an all-star pashing frenzy on the couch.
