1- Compasses. Both because they have the capability to navigate ships across the seven seas and because there are people who actually know how to use them.
2- Fax machines. So retro, yet still mystifying.
3- Jon Hamm. Whatta man, whatta man, whatta man, whatta mighty good man… SALT N PEPA to the max.
4- Grown-ass adults who can’t parallel park. It’s a life skill, learn it.
5- People who work in bakeries and don’t weigh 500 lbs. I would never last.
