I was helping a friend load some moving boxes into his vehicle, outside my house. I jogged back towards my front door to get the last two boxes - completely missing the step-up from the street sidewalk to my walkway, in the darkness - and then completely not missing the walkway as I stumbled and fell.
Ouch - sounds painful. By the by, aren’t pratfalls supposed to not actually hurt?
I can remember one incident of my own chin taking a beating. I was at a pool party when I was but a wee wrinkle in the spacetime continuum, and I jumped off the diving board a little too far to one side. Of course, you know what lies on the side of the pool - concrete. That one stung for a while.
Though the chin’s starting to bruise a little, and holds the current title for “most painful body part”, directly after the incident it was my noggin that was the champ - guess my brain bounced off the top of my skull a little.
By definition, you’d have to fall on your ass to make it a pratfall. Maybe of your chin/pavement encounter, you can claim to have gone “arse over teacups.”
