The answer is: TLC

"Way cool!" wasn't just a '90s catchphrase – it was the perfect description of how Nickelodeon leveled up their game when they landed TLC to perform the "All That" theme song.

Left Eye, T-Boz, and Chilli were already climbing the charts with "Ain't 2 Proud 2 Beg" when Nickelodeon came calling in 1994. The network wanted their new sketch comedy show to feel more "authentic" than the usual kid's fare. What better way than to recruit the coolest girl group in Atlanta?

The resulting theme song was a perfect match of swagger and silliness. Over a bouncing beat that screamed "1994," TLC delivered the now-legendary lines: "Fresh out the box / Stop, look, and watch / Ready yet, get set / It's All That!"

Those 30 seconds set the tone for what "All That" would become – a show that never talked down to kids while serving up genuinely funny sketches. The theme song's energy carried straight into classics like Pierre Escargot (Kenan Thompson's French character who could never quite master a lifeboat) and Coach Kreeton (Kel Mitchell's constantly-injured gym teacher).

But here's a detail that might blow your mind: TLC recorded the theme song around the same time they were making their diamond-certified album "CrazySexyCool." Imagine taking a break from recording "Waterfalls" to lay down tracks for a kids' show. That's range.

The theme evolved with the show through the seasons, getting remixed and updated as "All That" brought in new cast members. When the show returned in 2019, they kept TLC's core version but added a new twist: original cast member Kenan Thompson got to add his own line to the intro.

It's fitting that both TLC and "All That" alum Kenan Thompson went on to become icons in their own right. While TLC was changing the game with songs like "No Scrubs," Kenan was making his way to SNL, where he'd eventually break the record for longest-tenured cast member.

So next time you hear those opening beats, remember: that's not just any theme song. That's TLC, helping launch what would become Nickelodeon's longest-running live action series (a title it lost while off the air and regained during its revival). Now that's what we call way cool.
