I posted this on GameFAQs but I thought I'd also talk about it here and see what people on this board think.
WARNING SPOILERS for Ep 18 and 21!
I just finished watching 21 and it was a beautiful episode except for the part with those *** brothers, at first I laughed at the Mario and Luigi thing but then the thing got disgusting and just not funny anymore, same with Episode 18 where Morita decided to go back to college at the end.
They should really lay off the goofy humor, it's getting old, it feels forced at times. They can still make the series funny without this crap.
