Errors in geography
It was the phone book on the back page it shows Trowburg's when Shaggy first shows the book in the mirror you can see it spelled backwards with the letters backwards and the 's at the beginning. The second time you see the book it spelled Grubwort's with the 's at the end of word which would make it S'Trowburg instead of Trowburg's but the rest of the page is correctly backwards.
