They just can’t quit gloating.

A Philadelphia Eagles fan who apparently lives in Massachusetts is trolling the New England Patriots by purchasing an electronic billboard ad on Route 1 near Gillette Stadium that exults in the Eagles’ Super Bowl win over the Pats in February.

Those who are flocking to Foxborough on Thursday to watch the Patriots take on the Eagles in a preseason game will be likely to see it: The billboard — which shares a revolving spot with five other ads — was put up Monday, according to the company that owns it, and will stay there for four weeks.
