Basically a Hamilton version of both the "RickRoll" and "John Cena" memes.

You're just enjoying a nice, calm, and sweet YouTube video, with nothing to worry about, but then-

"HERCULES MULLIGAN!!!!!!!!!!"

Mulligan's rap from "Yorktown (The World Turned Upside Down)" plays.

Pretty random for some, if not, most people, right?
"Angelica!"
"Eliza!"
"And--"
"HERCULES MULLIGAN!!!!!!!!!!"
"You just got Mulligan'd, fool!"
Get the Mulligan'd mug.
