Michael Johnson and Justin Gaethje will fight in Las Vegas in a week to close up this season of The Ultimate Fighter. The two exchanged barbs at the UFC’s summer press conference, and Gaethje revealed himself to be perhaps not the best shit-talker. Thursday, Johnson went at Gaethje and called him the product of incest.

“Did your mom have sex with her brother to have you, or was it her cousin or something?” Johnson asked.

“When I break you, we’ll see,” is a strange retort, but okay.
