Under the Spreading Blacksmith Shop

Andy Panda is helping his pop out in his blacksmith shop and expresses a desire of his to shoe a horse. Pop tells him he couldn't even shoe a fly (laughs!!!) and decides to prove it to him by taking him up on the offer... namely by disguising himself as a horse (named Charlie) to fool his son. Andy agrees to shoe "Charlie" but the plan goes awry when all manner of disaster befalls the disguised pop culminating in his swallowing several magnets. (imdb)
