Watch: Rob Gronkowski says he and his brothers sleep together

Rob Gronkowski says sometimes he and his five brothers all sleep in the same bed after a long night out, even if there are five separate beds provided for them. He's not really sure why they do this. Neither are we. 

“We're just ridiculous like that. We wake up and we're like, ‘Oh, hey Bro, good sleeping with you,’” said the Patriots tight end, who also claims to have only read 80% of a book he allegedly wrote. The new literature—an autobiography entitled “It's Good To Be Gronk”—was released earlier this month.
