This begs the question, "How does Arthur know what Gary Coleman's foot tastes like?" An unfortunate misunderstanding at the beach perhaps? Remember Gang, Keep it clean!
Prior to meeting Sheldon, Arthur was flying south for the winter. He happened to fly over Tallahassee, FL, and the Florida State University Circus program. There, a middle-aged Gary Coleman was working on his BA in trapeze. Arthur dipped to get a closer look at the action just as Gary began his practice run for the triple-flip. Two flips in, and GULP, Arhtur caught one of Gary's feet in his mouth. Once the feathers had cleared and the safety nets had been lowered, Gary survived intact, and Arthur headed to Rite-Aid to look for Tinactin for Tongues.
