I'm never very good at this sort of thing. There is a French phrase I remember seeing somewhere once. I don't remember the French for it, but it translates into English as (something like) "wit of the staircase".

IOW, that joke, retort, put-down, comeback, etc that you needed fifteen minutes ago and is now too late. I'm a past master at those. *G*

P.S. Does anyone know what that French phrase is? I tried putting "wit of the staircase" into Babelfish and got "esprit d'escalier". I suppose that's at least possible?
