Their 2001 PopOdyssey tour, which had them touring football stadiums, had them flying out over their audience on zip wires for "Space Cowboy" and fighting a evil wizard for "The Game Is Over".
Their 2013 reunion at the VMAs. While it was shorter than most fans would have liked, it was awesome enough that Lady Gaga jumped out of her seat and flailed around excitedly and Taylor Swift started crying Tears of Joy.
Their 2001 VMA performance featured a dance performance from Michael Jackson himself.
The same year they were invited to perform for Michael Jackson's 30th Anniversary Concert, singing "Dancing Machine" along side Michael and the briefly reunited Jackson 5.
If that wasn't enough, they also had the honor of inducting the King of Pop in the Rock & Roll Hall of Fame.
They were invited to sing the national anthem at the 2000 World Series, which they performed a cappella. They were booed until they started to sing, at which the crowd then fell silent and then started raucously cheering when the song was finished.
They can play instruments, just choose not to. Their tribute to the 60s and wholesale Shout-Out to That Thing You Do! had JC and Chris on vocals with Chris on guitar, Justin on bass, Joey on drums, and Lance on keyboards.
