If this doesn’t take TRPs through the roof, we don’t know what will. The Big Bang Theory’s entire star cast recently appeared The Tonight Show with Conan O’Brien but the chat quickly escalated to a kissing orgy.

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 90’s on the show Blossom.

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 snog.
