This show is for kids, and as for such, it is not meant to teach them anything. Its meant to be pure slapstick comedy which is supposed to make kids laugh.
And for most of the time the mischief the Rabbids do is really funny and entertaining. Sure, there are parts where the humor is kind of forced and you could almost say that you laugh out of politeness. But then this is outhweighted by those really dumb Rabbids making so funny things that you wet your pants.
So if you as parent want to only give to your kids only shows which have an educational value, steer away from Rabbids invasion. If you want to have some fun, give it a go.
