Mikey Day, 44, and Gosling, 43, were guests at the event on Tuesday, April 30.
They performed a live-action rendition of the Beavis and Butt-Head skit that had gone viral on Saturday Night Live on April 13th.
Gosling, dressed in a mint suit, posed for a typical picture session earlier in the evening with Emily Blunt, who is his costar.
Beavis, the cartoon character, made a triumphant comeback to the red carpet, this time donning the Death Rock t-shirt and shorts, a blond wig, and a prosthetic nose.
Original sketch: Heidi Gardner (Saturday Night Live) as a news reporter questioning a scientist (Kenan Thompson) on AI risks.
Due to their striking resemblance to the cartoon characters of the '90s, two members of the crowd, Jeff (Day) and Dean (Gosling), kept diverting Thompson's character's attention away from Gardner.
Thompson, a veteran of Saturday Night Live, keeps asking Jeff and Dean to get out from behind Gardner, 40, throughout the comedy.
Gardner had a hard time maintaining her composure as she initially turned to face Gosling.
