I should mention that the artist/creator of the Odd Rods (Odder Odd Rods, Oddest Odd Rods, etc), Ed (Big Daddy) Roth, died recently, so this thread is kinda appropriate, in a slightly behind-the-times sort of way.
I belive the MAD artist I was thinking of is Jack Davis, and his work does bear a strong resemblance to Big Daddy’s. Especially in the faces.
