Place this, win a bottlecap

[spatch]

Salvaged from a dream. Too familiar to be sure if it's mine or not. If it's mine, it's a damn funny thing to come up with in a dream. If it's not, it's still a decent one-line gag. Can't remember original premise, but OLD WOMAN is being detained by airport security (pre-2001 in the dream.) Setting's not important. Just need a skeptical authority figure and an OLD WOMAN who BELIEVES SHE IS A CHICKEN.

And what's with all these pictures of eggs?

OLD WOMAN
Those are my grandchildren!

I can't say I woke up chuckling, but I definitely remembered it, eh.
