The exact source of the Phoenix 50 of them line is not widely documented, so the clip has spread mainly as a standalone reaction sound rather than as a famous quote.

Shared on soundboards and in short form edits, this one became a shorthand for stunned counting, used whenever fifty of anything feels like far too many at once.
