I have to echo the previous comments alluding to Huck's voice, by Daws Butler, being based on Andy Griffith's drawl from his early comedy routines and southern characters, pre-Mayberry. Just listen to his routine called 'What it was Was Football', or his comedic take on explaining 'Romeo and Juliet', or watch his 'No Time for Sergeants'. I came across these old gems on the internet a couple of weeks ago after watching the PBS series about Pioneers of Television. One episode of the series, dealing with late night shows and their hosts, had a little bit of him on the old Steve Allen show telling these stories and I mentioned to my wife then that I thought the voice of Huck had to be based on Andy. I watched Huck's show starting with its debut in 1958 when I was 9 but I don't remember ever noticing the similarity before.
