PBR Jetpack Ad (1976)
In 1976 Pabst Blue Ribbon ran this TV ad of a man flying effortlessly with a jetpack.* Though the man we see at the end who takes off his helmet is just an actor, the man who actually flew in the ad was none other than William P. Suitor.
You know how we'll know when we're living in the future? When we finally see public service announcements warning us of the dangers of drunk jetpacking. Until then, just keep chugging hipster juice until your bed feels like a giant spinning hoverboard. Drink your way to the future!
*Technically, it's a rocket belt, but I'll let you nerds fight over that in the comments. Nerds.
