How I Met Your MotherSneak Preview: Britney's Big Return

1. Britney Spears, ya'all.

3. MarshallandLilySellTheirStuff.com is real and actually supports a children's hospital charity, because this show is awesome. However, GuyForcesHisWifetoDressinaGarbageBagfortheNextThreeYears.com appears not to be real, but I'm guessing it's only a matter of time...

Check out the actual How I Met Your Mother episode—Britney, stunt websites and all—this Monday on CBS at 8:30 p.m.
