Two gamechanging events loom over Monday's one-hour season finale of How I Met Your Mother: the likely reveal of Barney's (Neil Patrick Harris) future bride and the birth of Lily (Alyson Hannigan) and Marshall's (Jason Segel) first child.

And while the exact circumstances of the former won't be revealed until airtime, the former is a sure thing.

After going into labor at the end of the most recent episode, Lily's impending childbirth is now the subject of a quintessentially How I Met Your Mother pop up site, LilysInLabor.com. Little more than a "Team Baby" background and a video, the clip does feature Ted (Josh Radnor) amping up to the episode with some potentially too-literal-for-primetime-TV narration.

"Lily's cervix is dilating," he says, "and we want you all to be part of its grand opening."

Watch the complete video below, before "The Magician's Code," parts one and two, airs tonight on CBS at 8 p.m.
