NBC's Parks and Recreation doesn't return with new episodes until spring 2011, but they already have a bunch of fresh installments in the can. Shooting has been continuing into the summer so that pregnant star Amy Poehler can enjoy her maternity leave in the fall. Amy's co-star Aubrey Plaza, who plays April, says the cast had a particularly fun time shooting an upcoming episode that finds Amy's Leslie Knope putting together a time capsule.

"Leslie wants everyone to put something in there," says Aubrey. "Jerry (Jim O'Heir) puts in some really boring journals because Jerry's boring, and Leslie puts in a text book that she wrote herself about the history of the town."

This is the episode that features Saturday Night Live's Will Forte (of MacGruber fame) as a crazy townsperson obsessed with the Twilight series of vampire books. "He basically handcuffs himself to Leslie's desk because he wants to put a copy of Twilight in the time capsule and she won't let him," says Aubrey. Expect a twist in the end that won't be uncovered until future Pawnee denizens dig up the capsule. Teases Aubrey, "Let's just say it gets buried, but I'm not going to tell you what ends up in it."

Could it possibly departing cast member Paul Schneider, who played Mark? Wouldn't that be a twist!
