“Right now, the members of the Republican National Committee are
essentially the scientists in a movie realizing their creation has
escaped from the lab…”
Jimmy Kimmel

This, of course, is right after the terrified Republican National
Committee members in white lab coats, trapped behind glass with their
“creation,” are screaming for help as their nightmare rips them to
shreds.

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."
