Big Bang Theory: Kaley Cuoco’s on-screen husband Johnny Galecki pokes fun at romantic Valentine’s post

It left fans of the sitcom in hysterics

Johnny Galecki has entertained fans of The Big Bang Theory with his response to Kaley Cuoco’s Valentine’s Day post.

Galecki, who starred alongside Cuoco in the long-running CBS sitcom, has made a habit of poking fun at her romantic photos in the past.

On Sunday (14 February), Cuoco shared an image of her husband Karl Cook, writing: “Happy five years to the weirdest person I know! I don’t remember a moment before you entered my life... what a boring life that must have been! I love you.”

Galecki feigned jealousy in his response of “Um”, which alluded to the fact he played Cuoco’s on-screen husband, Leonard, for many years.

“Poor Leonard, don’t worry buddy she’ll never find a man like you,” one fan wrote, while another said the wry comment made them “spit out [their] drink”.

Cuoco played Penny in all 12 seasons of the comedy series, although she auditioned to play a very different role.

In a special featurette released by CBS ahead of the finale in 2019, the actor said she had tried out for the sitcom’s original unaired pilot, but failed to land the role of a character named Katie.
