In a moment that made every Fuller House fan lose their collective mind Friday night (Mar. 12), Bob Saget joined Carly Rae Jepsen onstage in Milwuakee to perform the show's theme song before a crowd of screaming adolescents. 

Video of the charade surfaced on YouTube yesterday. Watch it above, and listen for the bit where Saget tells the crowd: "Keep your clothes on," just like the '90s sitcom dad that he is. 

While the duo has a blast onstage—and the crowd gets proportionally hyped—it's obvious that Saget doesn't know the lyrics, and depends on Carly Rae to keep him afloat. Jepsen reprised the original "Full House" theme song, "Everywhere You Look," for the Netflix reboot back in February
