This young Cubs fan's Grandpa Rossy costume may have just won Halloween

Cubs catcher David Ross, aka Grandpa Rossy, has reached legendary status this season. He has his own fan-run Instagram account, he became the oldest Cub to homer in a postseason game during the NLDS and Eddie Vedder dedicated the seventh-inning stretch to him during Game 5 of the World Series.
So, on Halloween night, one young North Sider fan paid tribute to the ancient, timeworn 39-year-old:

The cane, the beard, the forearm cheat sheet! Spot. On. John Lackey's son also paid tribute to the Fall Classic contenders -- dressing up as one of his favorite Cubs: Um, Kris Bryant.

Grandpa Rossy, himself, spent the afternoon with Jon Lester and is that Ryan Dempster?
