Last night, professional wrestler and actor John Cena stopped by Jimmy Fallon to chat about his role in the new movie Sisters, but it didn’t go at all how you would expect. Before Jimmy could even ask a real question, John stood up, the lights dimmed, and the music played as he reminisced about his childhood.

Turns out, John Cena has a lot of unfinished business in his past, including a fling with a young girl named Stacy Henderson, who moved away to California after John professed his love. They were seven years old, by the way.

Then, there’s his dog Ruffles, who embodies so many childhood memories that John just can’t seem to recreate. Why can’t John connect with his childhood self? Where did that young boy go?

Turns out, he’s backstage, played by musical guest Troye Sivan, who emerges from the curtains to greet his older self. Now that John can finally confront his inner child, there’s only one thing left for him to do—and it’s hilarious.
