grim fable
So it starts with a little singing bit about how it is fun to go to the museum, Then the song leader/"museum guide" tells you to look at an exhibit (a person or an object or something), then everybody else/the "museum visitors" chants back "Marvelous! Fantastic! What the fuck is that?", then the "museums guide" gives a funny explanation/joke about the thing they introduced. Then you sing the little song again, and the next verse with the next exhibit, and so on
Been looking for this song for years because I found it hilarious, but nobody can tell me how it goes and I can't find it online either
