There's a fetish (although I suppose it's so marginalised that it would be a kink) called pun-ishment which essentially consists of punishment by repeatedly making puns.

No, not like that.
I think it involves more spoken ambiguity like that which devious genies and those baring wishes always seem to play on in fiction.
And buttplugs obviously.
