X-Ray X-Perts - S2.E15

When Tennessee and Chumley are ordered by Stanley Livingston to get back the rare coin with which they accidentally paid the paper boy, they trace the coin's path to a bakery and then to a cookie from that bakery that Chumley ate. How shall they recover the coin? Tennessee and Chumley turn to Phineas J. Whoopee, who tells them about x-rays.
