Superpowers

I've always had trouble thinking up an answer to the question "If you could have ONE superpower what would you like it to be?"

I've finally thought of one: I would like to have the ability to hold time when someone is rude or nasty - or even just cheeky - to me in order to be able to think up a brilliant riposte.

(the phenomenon of thinking of a great comeback, but too late, is called "esprit de l'escalier".)

Can anyone think of a better one?
