10 Guest Stars We Want To See It's Always Sunny In Philadelphia

If there's one thing that seems to go down like a cold beer on a hot summer's day in this show, it's family connections.

With the marriage between Kaitlin Olson (Dee) and Rob McHelenney (Mac), Charlie Day's marriage to Mary Elizabeth Ellis (The Waitress) and even Glenn Howerton's spouse Jill Latiano making an appearance in the show, it seems that Always Sunny is a family business. So, why not continue that trend?

This charismatic star of the hit show Bones is the real-life partner to everyone's favourite street rat Rickety Cricket, otherwise known as David Hornsby. So seeing her dive into the world of It's Always Sunny In Philadelphia would go smoothly, and it could be hilarious to see how they connect her to her husband's character.

However, even without this connection, Emily Deschanel would still be a great choice as she's proven herself to be a very witty and charming performer thanks to her tenure in Bones.

She has an upbeat energy that would make her an uplifting part of the show, albeit one that the gang will probably tear down.
