The Flintstone-lookalike one for Fedex. That caveman who sent his mail by some bird dinosaur. It doesn't have the time to fly 10 feet before some T-Rex or whatever dinosaur eat its bird courier. He goes back to his office cavern and get fired by his boss, because he didn't used Fedex... but Fedex wasn't invented yet. The boss don't care a dime about it. So true.
