In the beginning of the Roman Empire Segment, one of the running jokes was the use of a V in place of a U. It seems that great care was taken to do this on every sign. Except the Annual Orgy sign which has two Us on it that were not changed to Vs. Us are also visible on the "Equal Opportunity Employer" sign at the Unemployment Office.

In the Spanish Inquisition musical number, the nuns do an underwater show that ends with them standing on a menorah. It is clearly visible in the movie that the action is in reverse.
