Looking smashing after delivering baby No. 2 in August, 'Parks and Recreation' star Amy Poehler returned to her old stomping grounds in midtown Manhattan to host the season premiere of 'Saturday Night Live,' using her monologue to recall a harrowing, stagefright-induced dream she had.

Tina Fey and Jimmy Fallon ('Weekend Update' co-anchors before Poehler got promoted to the big desk) snuck onstage to ratchet up the anxiety level, preceded by Kristen Wiig, who tried intimidating the nervous host with slick choreography.

But for just a moment, when popular 'SNL' guest Justin Timberlake (who's generating 'Social Network' Oscar buzz) strolled up and asked for a sexy smooch, Poehler's visions seemed downright dreamy.

Until JT gagged. Watch the whole monologue, and trippy dream sequence, in this clip.
