 "The Many Loves of Dobie Gillis: Dobie Versus the Machine (#2.21)" (1961)
Dobie Gillis: What I need now is somebody extra-wise, super-intelligent, a kind of combination of Einstein and Plato and Baruch and Shakespeare... 
Maynard G. Krebs: [enters scene] You rang? 
Herbert T. Gillis: No offense, Maynard, but if he rang, never was there such a wrong number. 

Maynard was the first tv character that seemed to speak to me, a lost high school kid who really kind of doubted everything and everyone. He was able to hold his own against the powers at the time that wanted to "make something of him" by making him a clone of themselves. I so loved that early free thinker. Well, he and Tuesday Weld.
