That episode of Get Smart where someone offers an invention/weapon to CONTROL... and the inventor turns out to be a young boy? Would have been much wiser and funnier by Brooks/Henry to have used a young "girly" girl in a pretty dress for that scene.

This was harder to find than I thought it would. The episode is "The Mysterious Dr. T." and found out something I wasn't aware of until I did a search. Peter Robbins also provided the voice of Charlie Brown in the early specials.
