(I am waiting in line at a fast food restaurant. The couple behind me, who looks to be in their late twenties, are discussing their orders.)

Guy: “Have you tried the bacon, mushroom and Swiss cheese burger?”

Girl: “Yeah, it wasn’t bad, but I’m not a huge fan of mushrooms.”

Guy: *starts singing super quietly* “Mushroom! Mushroom!”

Girl: *also super quietly* “It’s a snake! A snaaaaaake! A snaaaaake!”

Both: “Badger, badger, badger, badger, badger, badger, badger, badger!”

(They then go back to their conversation about various menu items, completely normal.)
