M.Ted: My memory of Hee Haw, concurs with yours. However, on the theory that I had merely forgotten, or missed, other examples of eephing and hamboning on Hee Haw, I did a Google search, using the words stringbean, hambone, hagers, and eephing in various combinations and came up with nothing. (Using stringbean and hambone together did bring up lots of soup recipes, however!)
