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

Anyone who's watched "The Gang Gets Quarantined" is fully aware that they adore the Philadelphia based R&B harmony group Boyz II Men. They spent almost the entire episode working on a cover of their classic "Motownphilly" to win a competition and perform alongside them. But fans never actually got to see the singers, which was a little disappointing.

While it might be tough to convince them to take part, there is a lot of potential in finally paying off this joke. It's been well-seeded, and the writers could work in a few more references to the popular group before they finally make their appearance, and it would undoubtedly blow the gang's mind.

They don't have much experience in TV - excluding a cameo in Marlon - but that wouldn't matter as all they'd need to do is turn up and be themselves.

The best story would be to continue the competition angle and actually see the gang get close to the end, only to be turned down and insulted by the group. Of course, this would probably cause a spectacularly angry reaction from Dennis, but then again, what doesn't?
