While I'm sure that a lot of work goes into being a part of the cast and crew of Parks and Recreation, it's hard to imagine that being on that set isn't a constant fun fest. At any moment, you could joke with Amy Poehler, talk TV with Retta, stare at Adam Scott or comb Nick Offerman's mustache. And how on Earth do they get anything done when they are constantly ruining takes by laughing? Because โ€” if the season 4 blooper reel is to be believed โ€” they sure do laugh a lot.
