Parks and Recreation is without question one of the greatest sitcoms of the last 20 years - a deliciously witty series that is at its core one of the most sweet, hopeful, and optimistic shows on all of television.
And like the very best TV series, Parks and Rec is filled to the brim with brilliantly subtle gags which reward both repeat viewers and those who are really paying attention the first time around.
Above all else, these ridiculous details are a testament to the insane amount of thought which clearly went into even the most seemingly unimportant visual or line of dialogue.
From absurdly long-term storytelling to ridiculously far-flung callbacks, secret cameos, and Easter eggs you'd likely never spot otherwise, these are the most mental hidden Parks and Rec details you absolutely need to see...
15. Leslie's Triplets Were Predicted In Season 2
Parks and Rec was absolutely jam-packed with clever foreshadowing throughout its run, but perhaps never more brilliantly than as it pertains to Leslie's (Amy Poehler) family.
In season six, we learn that Leslie and Ben (Adam Scott) are pregnant with triplets, a plotline that was secretly hinted at all the way back in season two.
In the episode "The Set Up," Leslie goes on a blind date with creepy MRI technician Chris - played by Poehler's then-husband Will Arnett - who tells her after the procedure, "You've got a great oven. Honestly, if you wanted to, you could go triplets right off the bat, Leslie."
At the time it seemed like nothing more than a throwaway comment, of course, but brilliantly it ended up being totally on the money.
