What movie is this from?

The girl in the movie is some sort of museum/art lady.

In it there is a crazy guy that dresses up as animals and takes
pictures of himself. There is a scene where the guy breaks into this
crazy artists house and finds him and two girls dressed as birds.

There is also another scene where he is taking pictures of himself
with goat legs and horns, dancing around the museum lady. WHAT MOVIE
IS THIS? It's driving me crazy lol
