Have you ever watched "Full House" -- or a yogurt commercial -- and wondered, "What is John Stamos hiding beneath that fabulous head of Greek hair?"
The "Necessary Roughness" actor posted a photo of himself on Instagram wearing a bald cap, and taught us all that a bareheaded John Stamos is not our favorite John Stamos.
Without a full head of hair for balance, Stamos' eyebrows, gold chain and velvet robe dominate the image.
In the '90s, Stamos captured our hearts, even after he cut his hair into a crazy mullet, a look which he resurrected for his "Full House" reunion on Jimmy Fallon.
You be the judge as to whether or not Stamos can pull off his most recent Walter White look. And for the Uncle Jesse purists, remember that it's just a bald cap.
