Fate subjects a character to circumstances that are notably ironic in the context of that same character's own designs and past actions.

Notes:
This theme does not apply if the irony is achieved through the considered designs of another character, for example as vengeance. It must also be reasonably clear that irony is a considered component of the story.

Examples:
In talesoftheunexpected3x06 "Parson's Pleasure", Cyril Boggis purchased a priceless commode for a pittance by telling the seller he needed only the legs and would use the rest as kindling. Upon appearing to collect it he found, in an ironic twist of fate, that the exuberant seller had decided to do him the favor of detaching the legs and chopping the body up into an easily transportable kindling pile.
