This reminds me of a product I used to see in a pilot's accessories catalog my dad used to get called Sporty's. They had this jug you could put in your small plane for those long trips when you might have to take a leak and they called it the "Little John", lol. Then you could order the upgrade option for your "Little John" called the "Lady J" adapter, hahahaha. Looked just like that and it fit over the spout of the thing. I used to crack up every time I saw it.
