As Hart explained, he and Rock were about to do another show that night, but their Saturday performance was particularly special because Dave Chappelle had decided to open for them.

And when they were arranging this, Hart let Chappelle in on a secret surprise he had for Rock.

And as ET Canada quoted him as saying, "He’s a large part of the reason that I am where I am today in my career just from his advice, his insight, et cetera and he’s my G.O.A.T. [greatest of all time.]”

So after all three comedians had done their respective things, Hart closed out the show with a special way to tell Rock how much he means to him.

As Hart added, "I wanted him to feel that and understand how I feel about him in front of that audience.”

And when he called for the audience to cheer for Rock after giving him the goat, it quickly turned emotional.

As Hart put it, "I gave him the goat. He almost cried. He almost broke down and cried on stage… it was a real moment."

That's because the goat not only defecated on stage soon after that moment, but did so all over Rock's shoes.

As Hart explained, "He destroyed Chris’s shoes. Chris had on some white moon boots and that goat got him."

Rock obviously wasn't pleased by this development, but I guess we can say it made the moment all the more unforgettable.
