Kaley Cuoco reveals ‘terrifying’ encounter with Big Bang Theory fan on plane

‘In hindsight, maybe she regrets it,’ actor said

Kaley Cuoco has shared a “terrifying” encounter she had with a fan of The Big Bang Theory.

The actor, who played Penny in the CBS sitcom, said the moment occurred on a aeroplane while she was “really engrossed” in a film.

Speaking to USA Today, Cuoco said that “out of nowhere” a flight attendant “came up and went, ‘Penny, Penny’,” before she “started knocking” in her direction.

Cuoco had no idea what the flight attendant was doing until later, when she realised she had been imitating the habit of Jim Parsons’ Sheldon Cooper.

In the series, Sheldon knocks three times to ensure he’s not walking in on something he shouldn’t be seeing. 

Explaining his reasoning to Penny, Sheldon says: “The first one's traditional, but two and three are for people to get their pants on.”

Cuoco continued: “It was, like, terrifying. And I could tell [from] her face, she goes, ‘I’m so sorry,’ but “I’m like, ‘That’s OK – why are you knocking?’ It wasn’t registering."

“I know the flight attendant thought this was very funny and in hindsight, maybe she now regrets it,” the actor said.

Cuoco plays a flight attendant in a new mystery series, aptly titled The Flight Attendant, which airs on HBO Max.
