Baseball players used to be widely known for chewing (and spitting) tobacco. When players began quitting the disgusting habit, a couple of them came up with an interesting substitute: bubble gum, shredded and packed in a foil-lined pouch to keep it fresh and soft (kinda like chewing tobacco is shredded and packed in a foil-lined pouch to keep it fresh and soft). The product caught on, and the players decided to market it to the public too. They called it "Big League Chew", and it's just celebrated its 20th anniversary.
And so we see the rapid decline of Mr.Baio. From promising hoodlum (Bugsy Malone) to commenting on a drug that hardly ever gets used anymore. Poor chap.
