Alfred E. Neuman is the fictional mascot of Mad Magazine.
Neuman's famous catch phrase is the intellectually uncurious "What, me worry?" This was changed for one issue to "Yes, me worry!" after the Three Mile Island nuclear meltdown in 1979. On the cover of current printings of the paperback The Ides of Mad, as rendered by long-time cover artist Norman Mingo, Alfred is portrayed as a Roman bust with his catch phrase engraved on the base, translated, of course, into Latin-- Quid, Me Vexari?
