The Declaration of Independence disappears from the sidewalk, then later reappears, and the body of the KO'ed thief also relocates itself on the sidewalk between shots.
There are two errors on the electronic score sheet at the bowling alley. Rick's current score, in the eighth frame column, is reflected as 52, but his score in the total column is reflected as only 38. William's score after one frame is listed as 16, but it should only be 13 (10 pins for a strike in the first frame, plus 3 pins on his next two rolls in the second frame). William's score is reflected correctly thereafter.
