Instructables member tomatoskins recently got married. As a result, he’s been on the receiving end of a lot of advice about how to have a happy, trouble-free marriage. He’s been told that one of the challenges of marriage that a couple might fight over the most insignificant issues as they combine households, such as which end of the toothpaste tube to squeeze from.
To head off that problem, tomato skins made a double-headed toothpaste tube. It consists of two toothpaste tubes which have been joined together at the bottom. Now, no matter what end he or his wife squeezes from, it’ll be the right one.
But the problem became a handy shortcut to represent the different ways people do things, and how irritating that can be.
