On “The Late Show, ” Steven Colbert reported that an Italian firm has designed stand-up airplane seats.

Colbert pointed out that, if you’re standing up, it’s not a seat.

He added that the only remaining way to cram more people on an airplane would be to put everyone in a pile. Do you think first class would be on the top, or would they get on first, like they do now?

The good thing about the pile? No seat belts needed.
