Dean and Sam in “Unfinished Business”

Dean

You know what video would have gone viral, if we still had it? When you were five and you got dressed up as Batman and you jumped off the shed 'cause you thought you could fly.

Sam

After you jumped first.

Dean

Hey, I was nine, and I was dressed up like superman, okay? Everybody knows that Batman can't fly.

Sam

[chuckling] Well, I didn't know that. I broke my arm.

Dean

[laughing] I know you did. Man, I drove you to the E.R. on my handlebars. Hm, good times.
