Between funky or funny, which fits the best?

funny teacher with funny students in a funny classroom. * I would go with funny it sounds better but a funny classroom doesn't sound right either. A funky classroom though would be a classroom that is weird not exactly funny or humerous*
What is funny about the teacher? His humour. He jokes in a weird way. He talks about not relevant topics such as having a boyfriend or a girlfriend, or the way you celebrated Christmas and so on. He mentions that holidays are made not only to rest but also to prepare for upcoming exams.
The students are funny, because they joke and talk about how great partying was. *not sure if this last line is exactly what you were trying to say but it sounds better in english*
