But in a fit of random cheapness, he gave them so little money that they returned with just frames with stock photos instead of framed actual pictures, figuring they could get pictures later. The stock photos were of spoons.

Tommy Wiseau decided that he liked the spoons. So the rooms have framed photos of plastic spoons.
