Barry Sanders, one of the best running backs in NFL history, spent the entirety of his professional football career playing Detroit Lions home games at the Pontiac Silverdome. The team of course moved on to the much more cushy Ford Field, but the old Silverdome holds a special place in the hearts of Lions fans and perhaps even Sanders himself.
Somehow, someway — actually, a detailed chronology follows — Sanders ended up autographing a Silverdome urinal and that odd piece of memorabilia currently is available for purchase on eBay.
It merits adding that urinal receptacles are often a hot item from old stadiums.
