Chris Rock — the exec producer of FX’s late-night show “Totally Biased With W. Kamau Bell” — famously suggested years ago in his standup routine that guns should be made available to anyone, but that bullets should cost $5,000 a pop.

On Wednesday, Rock updated that line: He suggested that instead, only those who have mortgages should be allowed to own guns.

“The gun lobby. . .says people need to be able to protect their property, but every mass shooting is done by guys who live with their mother.”

“So I believe you should need to have a mortgage to buy a gun. A mortgage is a real background check.”
