Lenny Shecter's version: When the Mets returned to the Polo Grounds to play the Cardinals on Opening Day [1963], the fans were already in mid-season form. One of their banners read: "BRING BACK BUTTERBALL BOTZ." Botz, Shecter also noted, "was so bad Dawes Hamilt could hit line drives off him." Shecter's version, in which a fan banner is the medium for the slogan, is the more familiar version. I tried surfing for that version, but could not find it, so I went with Isaac's tale instead. Did you type your post from Shecter's book? Yup. Maybe they both had it. People yell and write LET'S GO METS.
