FS1 Trolls ESPN With Skip Bayless Billboards

Skip Bayless just left ESPN -- but he still lives on in Bristol -- courtesy of his new employer, FS1, which just put up a handful of billboards trolling the mothership right in the center of ESPN country.

Of course, Skip recently ended his 23 year run on ESPN and is about to launch his new show, "Undisputed," on FS1 ... which debuts next week.

Which is why it's probably no coincidence that a couple of billboards just went up on a main road near ESPN headquarters -- where ESPN staffers will undoubtedly notice them.

By the way, the ads happen to show an image of Skip freeing a bird from its cage.
