Superstitions

Wouldn't it be funny to start your own superstitions. There are so many random ones out there. Like dont put your hands above your head, the cord will wrap. Or itchy palms means money is coming, etc..pregnancy related or not, they're typically silly. What if you made up that it was bad to smell your farts during pregnancy. So say you're pregnant and you have to fart. You fart and then run out of the room so you don't smell it so you don't harm the baby. That's the best I could come up with, but it sounds so funny to just make up the most random thing and have it catch on.
