Is there a name for this type of sentence structure: “She looks as though she's been poured into her clothes, and forgot to say 'when'”?
Is there a term for sentences which are an altered form of a famous quote, the alteration being a change in the second part of it for humor?
To err is human, to forgive is not a company policy.
A bird in hand might sh*t on your wrist.
People living in glass houses should use public restrooms.
If you can keep your head when everyone around you are losing theirs, you're probably the executioner.
I remember there was a term for such sentences but cannot recall. What is it?
EDIT: I also remember: It's not just with famous quotes — any sentence which sounds normal at first, but has an unexpected ending to it which compels you to re-read the first part, is also classified as the same thing.
