In a voice-over, Saget!Ted explains the whole thing, because of course Marshall isn't suicidal. He's just fixated on the lovely rooftop patio at the building next door. It even has a hot tub. We flash back a few years go. Barney, Marshall and Ted are on Ted's roof, filling up a kiddie-pool and gazing longingly at the landscaped, garden-paradise rooftop next door. Marshall decides he could jump to the next roof. He climbed to the ledge and psyched himself up, and... one hour later, he was still there. He repeated this scene occasionally over the next few years (including, hysterically enough, in a Dracula costume at a rooftop Halloween party), but he never, ever jumped. We flash forward to the current night...

Up On a Roof: Lily tries to talk Marshall down, but he thinks the jump is just the thing to turn his lame party around, and says, "Lily, when Evel Knievel sat astride his star-spangled rocket on the rim of Snake River Canyon, do you think his wife said, 'Honey, get down from there'?" Lily raises her voice. "For the last time, I am not Linda Knievel. I will never be Linda Knievel." Marshall sneers. "You don't need to remind me." That's probably just as well, because Linda and Evel divorced after nearly 40 years of marriage. We cut to...

Ted's Apartment: THE GOAT runs through Ted's living room, but Ted is so absorbed in his work that he only sort of catches sight of it, then shakes his head as if he's seeing things. We cut back to...

Up On a Roof: Lily begs Marshall not to jump, but when he won't stop, she says, "You want a reason? I'll give you a reason. I'm... pregnant." Marshall gasps and puts his hand to his chest. "Oh my God. Oh my God." He gets down from the ledge. "Are you really? Lily! I -- I mean I noticed that you'd gained some weight lately, but I didn't think you were..." It's Lily's turn to gasp, and she whacks him hard, for good measure. "I was lying, you jerk!" Hee. I should mention this episode was filmed out of sequence -- that is, much earlier in the season, before Alyson Hannigan's belly got really big. In fact, she only has a little Happy 31st Birthday card or whatever in front of her mid-section, throughout the episode, as opposed to the racks of basketballs, guitars and whatnot it took to cover up evidence of Satyana Denisof's existence, later in the season. Similarly, Cobie Smulders wasn't even really showing at all. Watching the actresses' pregnancies progress throughout the season has become a bit of a pastime for me (and many), so this joke gag felt like a nice bit of fan service. At any rate, since Lily isn't pregnant at all, she's ticked that her husband said she's gained weight. "Oh, go ahead and jump. I hope you die." Marshall shrugs that off. "That's all the permission I need," and returns to his perch on the ledge. Ladies, I found marrying a man with several sisters to be a good life choice. Boys who grow up in a family of all boys? No offense. I'm just saying.
