Why is "Come on, man." funny?

Political

Who it channels

Joe Biden's debate-stage exasperation — the folksy, slightly weary brush-off.

Where it comes from

A Biden staple, most memorably from the 2020 debates, used to wave away an opponent's point without engaging it.

Why it lands

It is a rebuttal with no argument in it — pure avuncular disappointment. Anyone who watched the debates hears the exact delivery, so you never have to say whose voice it is.

How to drop it

Someone suggests pineapple belongs on pizza. Your entire reply: "Come on, man."
