Not that twin. His REAL twin.
When Robin Lopez goes to the barber, he brings a photo of Sideshow Bob from the Simpsons. Everyone agrees upon this. Lopez gets it, too, and he took to Instagram to provide us the ultimate confirmation that he was created in the image of Bart Simpson's adversary:
Please note that this photo comes with the hash-caption "#ILoveYouKelseyGrammer." Please note that Lopez also refers to Bob by his full name, Robert Terwilliger. Please finally note that Lopez's Instagram name is "gustogummi88." You can conclude your noting now and begin applauding.
