Friends Season 5 Episode 6 : The One With The Yeti
Emily's demands become more and more unreasonable, so Ross tells her she's got to trust him or their marriage won't work. Emily then tells him she can't trust him, and she and Ross decide to divorce. Monica and Rachel look for a waffle maker in the basement, the light falters and see a very hairy guy, who they mistake for a yeti. He then turns out to be their new neighbor, Danny.
