Another classic from Jay Ward who brought us Rocky and Bullwinkle, Dudley Dooright, George of the Jungle and Tom Slick.
I love this cartoon because it has jokes for kids and adults (ala WW2 era Bugs Bunny cartoons). For example, Henry's "Super Sauce" was served in a martini glass with an olive. I remeber watching this cartoon with my Dad and him laughing at stuff I didn't get. I also love the absurd villans such as the Zipper, Dr. Gizmo, Wild Ralph Hiccup, Merlin Brando and the Fat Man. Many of whom were pop culture references for the time (mid 60's). Lastly, I just love the theme song. If you want to hear it, just google "Super Chicken". There's a fan sight out there with lots of sound clips.
I wish they would put it out on DVD. Are you listening Jay Ward's estate???
