".........It's one of several artifacts that round out the exhibit, included alongside such unique objects as a 1963 Alfred E. Neuman Model Kit, a 1987 MAD Squirting Stapler, and, most amusing of all, a 1962 MAD LP featuring such songs as "When My Pimples Turned to Dimples" and "Please, Betty Jane (Shave Your Legs!)." Alfred E. Neuman, rock star? In this MAD MAD MAD MAD world, anything's possible.
