In the beginning of the movie, at the shoe factory. Alan accidentally shreds a shoe. Some time after that, you see a shot of Carl (the Sole Man) with his co-workers gathered around him. (Unfortunately I haven't seen the movie in a while so I can't remember EXACTLY what he said) He says something, I think it might be admission or an apology...but one of the men behind him mouths the words along with him. It's pretty easy to spot.
