How I Met Your Mother Season 3 Spoilers

Disclaimer: I am not an official source; just passing what I read from all over.

This was reported on TV Guide's Ausiello's blog and I am already laughing just reading it:

Marshall will give Barney a rather large clue about when his highly anticipated third slap will be delivered. (Hint: It involves a website called slapcountdown.com. Don't bother checking the site, though, there's nothing there. Yet.)

Slap bet, ha-ha!

Season 3 will also have:

• Lily and Marshall's apartment-hunting saga.
• Marshall rethinking his job direction: the job he wants vs. the money he needs.
• The woman who took away Barney's virginity. The are casting someone "frightening", a woman who is about 45 years old. ROTFL.
• The return of Barney's gay black brother, brother.
• Some hints about "Mother"
  

The show premieres in September 24.
