How I Met Your Mother Season 9 spoilers were served abundantly during the international Comic-Con in San Diego over the weekend. The five starts we've watched for eight years were present, but 'mother' Cristin Milioti was a no-show. The 20th Century production delighted the audience with a hilarious video showing Ted's kids in a mock HIMYM trailer.

Ted's kids in How I Met Your Mother Season 9 mock teaser are all grown-up. Lyndsy Fonseca and David Henrie bash their father (Bob Saget) in character. The HIMYM kids have been on the couch through puberty, without having felt the sun on their skin, and using a bucket for bathroom breaks! All the grown up kids want now is for dad to wrap it up. (Watch the video below.)

How I Met Your Mother Season 9: 'Major' Updates at Comic-Con 2013

To treat the fans, How I Met Your Mother was properly represented at the show's first and last appearance at the Comic-Con. Josh Radnor (Ted Mosby), Cobie Smulders (Robin Scherbatsky), Jason Segel (Marshall Eriksen), Neil Patrick Harris (Barney Stinson) and Alyson Hannigan (Lily Aldrin) are all present. With them are HIMYM co-creators Carter Bays and Craig Thomas, and director Pamela Fryman.

Here are some of the spoilers and insights the How I Met Your Mother panel revealed at the show's Comic-Con panel:

1. The entire HIMYM Season 9 is built within the framework of Robin's and Barney's weekend wedding. But the stories will cover "decades" of events in flashbacks and flash-forwards.

2. One episode is dedicated to one of the slaps in Marshall's and Barney's slapbet. It may or may not happen during the wedding. (Marshall and Lily have been seen in HIMYM Season 8 flash-forward, in which they are trying to stop a panic-crazed Barney from running away. This might be it.)

3. Josh tells the Comic-Con audience, "Everything happens for a reason in How I Met Your Mother, and there's something really lovely about that."

4. Another Robin Sparkles look-back might be coming. Carter Bays wouldn't confirm, but he teased: "People sing songs at weddings."

5. A lot of guest characters are coming back to take a bow with the gang during the course of How I Met Your Mother Season 9. They'll all meet the mother, too. Coby hopes to see Lucy Hale (Robin's sister) back.

6. How I Met Your Mother Season 9 is both a farewell treat to the fans, and a getting-to-know-the-mother chapter.
