1. They reintroduced acapella R&B to mainstream radio back in the '90s and are one of the best-selling groups of all time, with over 60 million albums sold.

2. The original Boyz II Men was actually a quartet--Nathan Morris (baritone), Wanya Morris (tenor), Shawn Stockman (tenor) and Michael McCary (bass). Then McCary got ill and retired in 2003. 

Just look at that swag.

3.  They pretty much dominated the Billboard charts that decade. "End of the Road" stayed at the top of the Billboard Hot 100 chart for 13 consecutive weeks.

"I'll Make Love to You" for 14 weeks

Which, in our recent memories, had a few seconds to shine in Pitch Perfect.

The song only lost the top spot to their own single, "On Bended Knee." 

4. And "One Sweet Day" feat. Mariah Carey stayed at the top for 16 weeks--the longest-running number one song in Billboard history. 

Accumulatively, they rank fourth for the longest time spent at number one in the Billboard chart. That's behind only Elvis, The Beatles and, of course, Mariah. 

How fab.

5. They have a philanthropic side too! The group has its own charity called Boyz II Men House, which raises money to improve the quality of life of those less fortunate.

6. They've actually been active over recent years, releasing albums like Throwback Vol. 1, The Remedy, Motown: A Journey Through HItsville USA, Love and Twenty. 

They've got 4 Grammys, 9 American Music Awards, 3 Soul Train Awards and 2 World Music Awards to show for it. 

7. Fun Fact: Once upon a Christmas, Boyz II Men featured Justin Bieber in the track "Fa La La." 

8. They have a regular show at The Mirage, Las Vegas. 

9. Only last October, they released their 11th studio album Collide.
