I can't think of a single example for this, there are just too many. Basically any pixar film is silly, but there is usually a decent plot in there.
Kung Fu Panda (both films) is very silly (almost constantly) but it has a serious plot as well. =]
I think it has the perfect balance, though that is also because I enjoy the particular humour in most Pixar films (the animation matches perfectly with the type of comedy they are writing, so it works well - you can have the right writing, but bad implementation and still come off all right, but generally it loses the reader/viewer/player when it doesn't match well).
