This is all I could find that seemed even somewhat related....
Wellerisms Involving Mention of a Wooden Leg
I see, said the blind man with a shake of his wooden leg, that the price of lumber has gone up.
I see, said the blind man as he peeped through the hole in grandpa's wooden leg (H.42).
I see, said the blind man as he spit through the knothole in his wooden leg (H. 45).
[...]And finally, our Wellerism probably shows contamination with another and quite unrelated Wellerism,
"'Aha,' she cried and waved her wooden leg." A more detailed analysis of these modern versions is unnecessary. They imply the existence of a flourishing oral tradition.
