However now that they've basically adopted Riverdale co-star KJ Apa as their third, long-lost twin... the jokes are even funnier.
While the cast were on The Tonight Show with Jimmy Fallon, Dylan was backstage being the supporting twin brother that he is.
However, when he got in a selfie with Cole and KJ, he noticed something pretty iconic going down.
Yep, they all have the same hair as the Powerpuff Girls, and we're LIVING for it.
Heck, they could even pass as the Rowdyruff Boys (throwback much?)
The best part is that Cole is a natural blonde, and KJ a natural brunette, but thanks to Riverdale this trio just became legendary.
Pls, raise your hands if you'd be keen to watch a remake of the PPG starring these three bae's?
