Betty White celebrated the start of the Super Bowl with the best cackling dab you'll see all year. It's at this point where we normally critique someone's dab form, but not Betty White -- she's perfect and untouchable like the first snow of winter. You are everything Betty White, and your dab was glorious.
Also of note: She made a semi-creepy comment about the dab by saying "I taught Dab everything he knows" in a very suggestive way. You keep on keeping on, Betty.
