Your funny/weird thing??

What is something that you and your SO do that some people may find funny or weird? My husband and I have a "naked animal" day once a week. It's not what you would think though. It's literally just the one day a week we take all of our pets collars off for the whole day so they get a break from them. We also have the weirdest names for each other. And we talk to each other in almost baby like voices a lot. We normally call each other "poopalie". (:
