ET caught up with the cast of the hit comedy-horror show earlier that day, where Stamos couldn't help but crack a couple jokes about being the newest "eye candy" to join the series. 

"Our first shot yesterday we came out of the elevator, they start on our shoes and they pan up," he told ET's Leanne Aguilera. "Then [executive producer] Brad [Falchuk] goes, 'John, could you grab yourself?'"

"I felt like a piece of meat day one!" he said.
