Good stuff, Maynard! 

Originally used in "The Many Lives of Dobie Gillis" a sit-com that ran from 1959 to 1963. The main character, Dobie Gillis, used it when talking with Maynard G. Krebs. Krebs was played by Bob Denver, who later became known as Gilligan of Gilligan's Island. The line was later used in a Malt-O Meal commercial.

"Hey, look how he fixed that! That's good stuff, Maynard!"
