Growing up, Uncle Jerry was my hero because he had one leg longer than the other. He’d show us kids. “Look, ma leeeft leeeg’s longer. Jus’ started that way when I’s fifteen. ‘Swhy I ne’er got called up.”
I noticed as a teen that sometimes his reet leeg was the longer, and then my Mum let slip how Uncle Jerry had a medal for valour. So I started to push a hip forward a little and tease my little cousins that I inherited Uncle Jerry’s condition and they’d better watch out in case one day they woke up the same.
Addendum: apologies to those who read the early version without the last word. Not sure how that got missed but I love your ideas as to what it should have been.
