'Saturday Night Live' comedian Jason Sudeikis and his lovely fiancee Olivia Wilde brought the yuks to Kansas City, Missouri to raise money for the cancer support group Gilda's Club, named after the late legendary 'SNL' comedienne Gilda Radner.

(You may recall some chapters of the club were poised to change their names in November of last year, but after some well-deserved backlash, they decided against it.)

Sudeikis, whose own mother survived cancer, joined comedy and improv troupe Second City (which has nurtured the likes of Tina Fey, Stephen Colbert and Amy Poehler) to bring the laughs, with Wilde joining in after the intermission.

They ended up raising $100,000 through ticket sales and donations.

A source for E! News who attended the event reported that while Wilde seemed nervous at first, she eventually got in the groove of things and gave an "absolutely adorable" performance with her husband-to-be.

"The evening was super funny and [they] interacted well with everyone there," the witness said, adding, "They seemed like the kind of couple that will be together for a long time."
