The Lonely Island started as a video thing, and they’ve almost never taken their act to a stage — any stage. Last night, however, they were musical guests on Jimmy Kimmel Live, where they performed the hashtag-rap grammar-nerd anthem “Semicolon.” Solange, who sings on the song’s recorded version wasn’t there. Instead, Alanis Morissette, of all people filled in, and found some room to riff on her own history with tortured definitions during the performance. This was generally all pretty great, and you can watch it below.

The Lonely Island’s guest-packed The Wack Album is out 6/11 on Republic, and Alanis isn’t on it. Who would’ve thought? It figures.
