In these two clips, you'll notice Axel taking his spyglass down to look thru it--that always meant it was time for a cartoon. And Axel always ended his show with "Birdie with the jello bill"...a Robert Louis Stevenson poem, but Axel changed the last line to a bad pun. THIS is humor!
(Thanks to the Bulletin Board column from the St Paul Pioneer Press this morning. I wasn't aware that any episodes of Axel were still around. Truly, he formed a good part of our senses of humor--ok, mine at least ☺)
