The Massachusetts native was among a bevy of A-list celebs who made cameo appearances on NBC's "Saturday Night Live" this weekend, as Kristen Wiig was inducted into the Five-Timers' Club.
Rudd, 55, has also hosted the show five times, and was the first celeb to pop up during Wiig's monologue Saturday night, April 6.
Then came former writer Paula Pell, and then, Damon, who grew up in Cambridge, donning a Five-timers' jacket.
"First off, big fan," 53-year-old Damon tells 50-year-old Wiig from the audience. "I grew up watching you on SNL."
"You grew up watching me on SNL?" Wiig replies. "Wait, Matt, why do you have on a Five-Timers jacket? Haven't you only hosted twice?"
"Yeah," Damon says, "but Lorne said the first time was so good it counted for three. And then, second time not quite as good that only counted for two but by my math, that's five baby."
Damon joined Wiig in other sketches in the evening, but not before hopping on stage alongside Jon Hamm, Fred Armisen, Martin Short, and more — all in Five-Timers jackets.
