Hmm, I think I get it. The plane said something so long it crashed. I think she said "our song". The animation was great. I especially enjoyed seeing how long the joke would go on. The title was kind of simple.
I loved that heart they made with their hair. Hey, it wasn't about cheating on somebody. That sounds like a happy enough ending for me! Did she say, "our son"? This was short, but well drawn enough.
