- Thomas (US): Gone? Gone! Now I'm really blue. And the only cure for the blues is more cowbell.
- Diesel (US): Yeah, you said it, brother.
- Thomas (US): Cowbell, oh cowbell! Hear me singing my lonesome plea! Cowbell, oh cowbell! Why didn't Percy give you back to me? Sharing you was fun, I know. But now I've hit an all new low... Why didn't Percy give you back to me? The rules of sharing are clear you see. You gotta give my stuff back to me. I really, really miss my shiny cowbell... I miss my bell, so much it's true! But sharing is the thing to do. My friends all like your clank and clink. It sure does make an engine think. If someone shared their toy with me. I'd give it back so easily. I really, really would. Cowbell, oh cowbell! Hear me singing my lonesome plea! Cowbell, oh cowbell! Why didn't Percy give you back to me?
