Willow and Oz are going to be together again. How I Met Your Mother, which stars Buffy witch Alyson Hannigan, will feature an awesome Buffy reunion when Seth Green guest stars in an episode later this season.

Green, who played Willow's high school werewolf boyfriend Oz, will guest star on the December 10 episode as a guy who went to college with Marshall and Lily and considered them his best friends even though they barely remember him. And it turns out he's still obsessed with them.

This is not the first Buffy alum to show up on Hannigan's new show. Other notable guest stars include:

-Harry Groener (the Mayor on Buffy, Ted's stepdad on HIMYM)

-Alexis Denisof (Watcher Wesley Wyndham-Pryce on Buffy, cocky news anchor Sandy Rivers on HIMYM and Hannigan's real-life husband)

-Danny Strong (Jonathan on Buffy, Marshall's pastor's son on HIMYM)

-Tom Lenk (Andrew on Buffy, a coffee shop employee on HIMYM)

Also, Seth Green isn't the first former werewolf to guest star on How I Met Your Mother this season. Joe Manganiello, who plays werewolf Alcide on True Blood, will return this season as Marshall's friend.

The reunion of Seth Green and Alyson Hannigan is something all Buffy fans can be excited. Now all we need is for HIMYM to cast Amber Benson as a girl Lily experimented with in college.
