Note to school districts: If you are going to produce a field-side banner aiming at increasing sponsorship via the sales of other similar banners, make sure that your own product is spell checked before it goes to the printers, and after it comes out. In particular, avoid the mistake made by the Red Lion Area School District -- a school district in Pennsylvania -- in the banner above, as first noted by Deadspin and originally posted to Twitter by Ryan Petzar. Go ahead and read the text on that sign twice. The spelling mistake is as embarrassing as it is...
