“Right now, the members of the Republican National Committee are
essentially the scientists in a movie realizing their creation has

Jimmy Kimmel

This, of course, is right after the terrified Republican National

Great metaphor on Kimmel’s part.

Oh, metaphor. Right, this is rec.boats. Sorry. Explanation:

"A metaphor is a figure of speech that identifies something as being the
same as some unrelated thing for rhetorical effect, thus highlighting
the similarities between the two."
