Season Finale: Parks and Recreation leaves us with one final clue?!

The 5th season finale of Parks and Recreation starts of with Leslie and her co-workers at Ron's cabin and the episode continues as Leslie expects the 1 year of Leslie Knope in the office forum to be a victory but things turn away from her at the parade where 300 Pawneen's recall Leslie Knope. The finale episode also brings back "The retired Burt Macklin"Andy who in the role of Goofy-detective runs through the list of suspects -who might be pregnant. This leaves the rest of the episode littered with clues. 


SO you watched the video? A little Ron with Mustache may be?! or who will be pregnant and not sharing the great news?
