Kinda reminds me of a Justice League clip I once saw. The team was talking about when to have the next meeting. Batman said he couldn't make it at the scheduled time, because his son Damien has a parent-teacher conference (yeah, Batman has a son... don't ask... it's a real fanfic thing that got worked into the mainstream comics.)
"Well, how about that evening?"
Flash says, "Oh, no can do. I got rehearsal that night."
"You're in a play?"
Batman says, "Flash is getting married... somehow." The implication is that Batman has a hard time believing Flash could find a woman who would marry him.
