Go to the special features, and then go to the deleted scenes. In the scene when Austin comes in through the elevater and does the clappy thingy to Felicity, the set is the same as in Wayne's World 2. The elevator is the same. Mike Myers was also the star of that movie.

Also, one of the deleted scenes has Dr.Evil doing a strange kick thing to Mini-me. That is from the movie "So I married an Ax Murderer" which also starred Mike Myers.
