It’s one of the most memorable, legendary, and laughter-inducing scenes in television history.
However, behind the scenes it wasn’t all fun and games.
Tirelli knew that she was supposed to have a fight with Ball, but that was it.

When Ball accidentally struck her for real during filming, her on-screen rival took offense off-screen.
“So she hauled off and let me have it,” Ball told Dick Cavett.
“This was supposed to happen.

That, she got right.
But when she hit me, oh my God.
She only came to about here [Ball’s chest].

She hit me right [in the stomach] and took all the wind out of me.”
“She kept me down by the throat!
“And I’m really beating her to get her off.
I was drowning in these grapes.”
