Delicious Gakuin - Episode 13 (Final) [3/3]

Part 3 of 3. Final Episode. But, there's a movie coming out in July. This series is so ridiculous. So, of course I'll have to get the movie too. :P

This last part makes me wonder whether or not Japanese people think there is actually HAM in HAMburger. If not, then why is one of the teachers wearing a "pork" hat when they're singing the Hamburger song??
