Did Bob get his old face back??? I hope so!

of course he did! on the episode "at long last leave" he has a tiny appearance, and he has his face back! woohoo! but on his next episode, it will probably explain it

Of course he'll get his face back. The Simpsons' reset button is permanently stuck. They may come up with a story around it next time we see him, but he'll be back to normal, assuredly.

sure it will, remember that the two faces could EASLY fall of. So why wouldnt they swap faces again???
