How much butter could a buttercup cup if a butter cup could cup butter?

The phrase "How much butter could a buttercup cup if a buttercup could cup butter" is a play on Words and does not have a literal answer. It combines the idea of a buttercup flower with the action of cupping butter. In reality, buttercups are flowers and cannot cup butter, so the question is nonsensical and meant to be a fun and whimsical Wordplay.
