Gob-Gob
A caveman, found preserved intact inside an iceberg by Superman in February 1949, who causes a sensation in Metropolis until he turns out to be nothing but a well-coached circus strong-man engaging in an elaborate hoax to publicize his forthcoming motion picture. (Act No. 129: "Lois Lane, Cavegirl!") (TGSB)
