I am afraid these are only remotely related, but here they are anyway.

Why did the chicken cross the road?

To prove to the armadillo that it could be done.

(That is likely only funny to Southerners, Northerners can substitute any number of possums for armadillo, but it just isn't the same.)

What did the banjo player do when he got lost in the woods?

He decided to follow the armadillo out to the road.

Herb, I'm sorry that I am no help on your original question, but after the first of the year when I go back to work, I will see what I can do to scrape that one up for you. (OK, I'm done!)
