I love it when worlds collide on TV. Like when Terry O’Quinn scored a gig on Hawaii Five-0 alongside former Lost pal Daniel Dae Kim. Or when Lisa Kudrow did a guest stint on Cougar Town. It’s simply fun to see our past faves on the small screen together again.

The latest good news for nostalgia addicts? Busy Philipps is going to visit her old Dawsons Creek buddy James Van Der Beek in the season premiere of Don’t Trust the B—- in Apartment 23. And that got us thinking: In a perfect world, what other reunions would fill us with glee? Oddly, none on Glee — but there are plenty of others that made our picks.

My ultimate guest star? In a fantasy world where everything I want comes true? George Clooney on The Good Wife, where he would play a hot doctor with legal troubles who crosses paths with Alicia (Clooney’s ER co-star Julianna Margulies) before starting a torrid love affair. Hey, I can daydream. And since that’s sort of a specialty here at EW, here are some of my colleagues’ picks. Chime in with yours below:

Denise Warner:

Sarah Michelle Gellar on Bones!!!

Laura Hertzfeld:

The whole Friends crew needs to show up on Episodes and I would love to see Jared Leto pop up as some sort of secret agent/terrorist on Homeland.

Jeff Labrecque:

Katey Sagal on Modern Family!

Mike Bruno:

…Or Ted McGinley!

Hillary Busis:

I’d love to see either Amy Poehler or Tina Fey guest star on, respectively, 30 Rock or Parks and Recreation. Jimmy Fallon could come too. I’m also yearning for a Boy Meets World reunion… but in order for that to happen, one of its stars would have to snag a role on a current TV show.

Emily Rome:

+ Alexis Bledel on Supernatural (with Jared Padalecki)

+ Joseph Gordon-Levitt on New Girl (with Zooey Deschanel)

+ Any of the Firefly cast on Suits (with Gina Torres)

Chris Cosgrove:

I second that Joseph Gordon-Levitt & Zooey suggestion!

Lanford Beard:

+ Max Casella (Vinnie!) on HIMYM — How has this never happened?

+ Paul Rudd as an obsessed ex-boyfriend on The Mindy Project

+ Shiri Appleby as Jack’s new love interest on Revenge (no more pregnant Fauxmanda!)

+ Kristen Wiig/Maya Rudolph/Wendi McLendon-Covey/Ellie Kemper on Mike & Molly

+ A giant wooden cross on Person of Interest (ohhhhh, I’m only kidding)

Erin Strecker:

Adam Brody on Hart of Dixie!

Martin Schwartz:

Holly Hunter and Harvey Keitel on True Blood

Connie Yu:

Tricia Helfer and Grace Park (Hawaii Five-0)

Maane Khatchatourian:

+ Christina Applegate on Modern Family (with Ed O’Neill)

+ Chloe Sevigny on Once Upon a Time

+ Eric McCormack on Smash

+ Jerry Seinfeld on Veep (with Julia Louis-Dreyfus)

+ Zach Galifianakis on The Office (with Ed Helms)
