#8 The Winning Cap
Back in the ’90s, Dr. Pepper ran a promotion where you could win stuff from the bottle caps, including a free Dr. Pepper. I learned that you could look up into the bottle and kind of make out what was written on the inside of the cap. I bought one Dr. Pepper and continued to “win” many more Dr. Peppers. As a teen, having an unlimited supply of soda was amazing.
