Sometimes inspiration strikes as nature calls.

Back in October 2008, the Saturday Night Live gang was eating dinner at one of creator Lorne Michaels‘ regular restaurants, Lattanzi, to toast the week’s host, Jon Hamm, before heading back to the office to crank out the week’s script.

“And I remember,” Seth Meyers said on a recent episode of The Lonely Island and Seth Meyers Podcast. “I went to the bathroom on our way out, and I walked out of the bathroom and saw Andy [Samberg], and I said, ‘I just had a sketch idea: Jon Hamm’s John Ham, the ham you could eat in the bathroom.’ And you said, ‘Write it up!'” he recalled to his former costar.

In the sketch, Hamm explains the role of an ad executive, which he would know from his part at the time playing Mad Men‘s Don Draper. He said that he was there to speak to the audience about a product that didn’t need “any glitz or gloss,” because it spoke for itself. As sentimental music played in the background, he said that, with John Ham, people would never again have to make the choice of whether to spend their lunch break eating or going to the bathroom. The meat was located in stalls, on a dispenser opposite the ones for toilet paper. He demonstrated by pulling some of the meat off and taking a bite, which elicited big laughs.

The sketch aired on October 25, 2008, the first of three times that The Morning Show actor has spent a week in Studio 8H. Hamm, who has popped up for frequent cameos over the years, is scheduled to host for a fourth time — just one away from the Five-Timers Club! — on April 12.

Meyers said there aren’t many other sketches he can recall the exact moment he wrote them.

“By the way, I’m not like talking about it like it’s incredible or anything,” Meyers told his cohosts, including Samberg, who reassured him it worked.

“I can talk about it without the worry of having been the one to write it, Seth,” Samberg said. “It’s a perfect host piece. It’s a moment that Jon Ham as an idea is red hot in the world, and everyone’s super amped that he’s on, and everyone loves Mad Men. Except me, because I hadn’t seen it, but it just immediately is what SNL‘s about.”

Meyers said that he’d written it “in the time it took you to watch it,” but he seemed proud.

“Jon Hamm, two minutes. Again, in and out. Doesn’t waste any time,” Meyers said. “I rewatched it, and it made me happy.”
