My youngest brother had a lisp and one day asked, "Why do they always thay I'm full of pith and vinegar? I don't like it. They shouldn't be being mean to me and ith's naughty to be talking about pithing."
When my mother and grandmother saw the pain in his eyes they struggled out of their hilarity, wiped the tears from their eyes, and his. and said he was right and they would tell everyone to stop being naughty.
"Pith" was changed to "crusty," a tip of the tongue to the exquisite crust on a perfect bagette.
