Of all the “Parks and Recreation” cast-members, Chris Pratt has come perhaps the farthest, transitioning from little-known WB star (remember "Everwood"!?) to one of the world’s biggest action heroes over the course of seven seasons. So naturally the “Parks” gang couldn’t resist throwing a little “Guardians of the Galaxy" easter egg into the series finale last night, when a trick-or-treater shows up to Andy and April’s future home dressed as none other than "Star-Lord" Peter Quill. The scene is set in 2022 (about three reboots away in Marvel time) so we’re glad to see “Guardians” fandom is still going strong. One question, though: Why did none of them decide to go as dancing baby Groot?
