Weirdest I ever came across from the mouth of anyone else was someone that joined our form in Year 9 or 10, can’t remember which.
He claimed (way too vehemently, considering what he was to tell us) that he used to remove his eyes from his eye sockets at night and keep them in a glass of water, like you would dentures. Sometimes he wasn’t sure which eye was right and which was left, so would replace them in the incorrect sockets, it was only when he’d put his shoes on the incorrect feet that he would realise he’d put his eyes back in wrong.
Number of times we asked him for a demonstration but he claimed he wasn’t able to take them out during daylight hours as he’d go blind.
