Decoys is the 16th episode of Season 6 on NBC series Frasier.
Synopsis
OH WHAT A TANGLED WEB WE WEAVE -- A conniving Niles (David Hyde Pierce) schemes to play matchmaker with Roz (Peri Gilpin) and her former attorney/boyfriend (Saul Rubinek) -- who's now romancing Daphne (Jane Leeves) -- when he disingenuosly invites them all to a mountain cottage so that he can at last declare his love for Daphne. But Niles' best-laid plans are waylaid when an unsuspecting Frasier (Kelsey Grammer) and Martin (John Mahoney) show up a day early for some duck-hunting and 'fowl up' the lovebirds' nest.
