The principal comissions a picture play targeted at children, and the Sket-dan decide to use Momotaro as a template. However, Bossun and Switch create a random, rambling tale that isn’t suitable for anyone, let alone children, and is summarily rejected. Later, the principal asks the Sket-dan to babysit his rich, standoffish grandson, and find he’s immune to their charms…until they go outside and make him play baseball.
The thing about parodies is, if you aren’t familiar with the source material, it’s hard to know exactly what’s going on or why it should be funny. I don’t know anything about Momotaro, and yet the Sket-dan’s parody was still funny because it was so wildly ridiculous in its presentation. Himeko’s constant feedback was also entertaining.
The second segment is funny because it shows how zany and immature Sket-dan can be, and how maturity sometimes has nothing to do with age. Yoshihiko may be ten or so, but he may as well be forty. He doesn’t have friends or fun like kids his age should. He even fears getting his expensive clothes dirty if he plays. So it’s good that Bossun & Co. were eventually able to coax the kid into a semblance of a childhood.
