antiproverb

A humorous adaptation of one or more existing proverbs.

The system isn’t broken. It’s fixed.¶ Another species of anti-proverb, this one plays on the phrase “If it ain’t broke, don’t fix it” which seems to have emerged in the 1960s.

A proverb that contradicts another.

But for every proverb there is an antiproverb ("Too many cooks spoil the broth" vs. "Two heads are better than one," and so on).
