Jon Hamm Hilariously Parodies James Kennedy on ‘WWHL’: “You’re a Worm With a Mustache!”

If Tom Sandoval and Raquel Leviss decide not to come back to Vanderpump Rules, Jon Hamm and John Slattery may just be the perfect duo to replace them. During Tuesday night’s (June 13) episode of Watch What Happens Live, the esteemed Mad Men actors took on the “roles of a lifetime” as they reenacted iconic moments from the Pump Rules reunion.

In the latest installment of “Clubhouse Playhouse,” Hamm played the part of DJ James Kennedy while Slattery assumed the role of Sandoval — who was utterly steamrolled by his fellow castmate during the three-part reunion, which filmed weeks after his months-long affair with Leviss was uncovered by his girlfriend of nine years, Ariana Madix.

Stepping in front of a green screen, Hamm — English accent and all — exclaimed, “You’ve always been an opportunist!” to which Slattery (as Sandoval) fired back, “And opportunist? You fucked Kristen [Doute] to get on the show. You used my condoms! I’ve stood up for you!”

Hamm continued to hurl Kennedy’s memorable insults at Slattery — which ranged from “worm with a mustache” to “pussy ass bitch” to “backstabbing hoe.”

Meanwhile, Slattery, who was clearly not as much of a Bravo aficionado as his Mad Men co-star, asked, “Am I supposed to have an English accent?” to which Hamm replied, “No, you don’t,” before continuing the scene.

“Yeah, I’ll be quiet for tweedle-dee and tweedle-little dick. I’m gonna get sent for a time out — get a spanked bottom, Andy, at lunchtime!” he called out, while the camera cut to host Andy Cohen, who was in hysterics.

Hamm concluded the scene by declaring, “You’re used to living in shit. Poopoo head! Poopoo heads!”

Overall, we learned two things from this — shall we say, “Good as Gold” — performance. One: that these actors need an Oscar, ASAP. And two: that Kennedy’s creative trash-talking is even more hilarious coming from the mouths of two middle-aged men.
