A horse pulling an attractive female frog throws a shoe. Luckily for them, the village smitty is right there so the horse - the most entertaining character in the cartoon - goes to get re- soled. A few wacky things happen after that, thanks to a pretty funny but brutal horse fly.
Overall, it's dated but it has enough sight gags to make it worth a look. This was the fourth cartoon in a series of old ones in a DVD called "Cartoons That Time Forget: The UB Iwerks Collection Vol. 1."
