Copycats in Super Bowl Props

In my book, I wrote about a Las Vegas sportsbook that copied Super Bowl prop lines and made a mistake that cost them. I found another one a minute ago:

Kevin Faulk's longest rushing attempt will be over/under 3.5 yards.

I took the Over at -110.

The book mis-copied the line. The prop should have been: Kevin Faulk's FIRST rushing attempt. Faulk may not rush many times, so I may still lose, but this bet has great value. Now I just have to hope that they don't notice their mistake and cancel my wager...and if they allow it, they don't grade it incorrectly once the game ends. Books that mis-copy lines also tend to have a greater frequency of mis-grading winners/losers.
