Years ago I got a call for someone who had been bouncing on a trampolene, while intoxicated, had smacked his face on the outer metal rim. Normal this would have been an uneventful call except that the man had braces, and some kind of retainer or palate expander.
So when he hit, the metal and plastic broke off partially and was rammed half down his throat.
The patient remained calm, I don't think he realized his peril at that moment, and allowed me to use magill forceps and manipulate the plastic and metal back up his throat and used tin snips to cut the mangled mess away.
He said thanks, I will go to my orthodontist tomorrow. I advised him against this. , but it was his party and there was no way to get him to leave. Called command had them talk to him, signed him off and was offered beer and cake to take back to the station.
