What's your one line comeback to the slap, that's better than what Chris came up with

"Will Smith still hasn't made a solid hit since Independence Day."

"You're moving with your auntie and uncle in Bel-Air."

For the rest of his speech, Rock should have pretended he was going to mention Smith's wife again, just to keep him on the edge of his seat.

"Yada yada yada, people will gossip about this incident for years"
"Mrs. Smith is the one with the balls, you know the movie Mr. and Mrs. Smith?"
"Pinkett or pinkish, what do you call this color?"

Suggestions?

"Apparently you can f*** his wife but can't say her name."

"I wonder what teachable moment Uncle Phil would have made out of this."

"Will Smith 'bout to be the first man to win an Oscar after going full retard"

"Damn ! Almost makes me wish I was THE Rock instead of Chris Rock."
Then maybe he could flex a Duane Johnson pose and raise an eyebrow like Duane.

Damn! Bagger Vance just smacked the shit outta me!

or

James West just bum rushed me!
