Gronk reveals parents' 2 rules for fights between brothers

According to Rob Gronkowski, his parents only had two rules about brawls between he and his brothers when growing up: No punches to the face, and no punches below the belt.

"I'm all about (those rules)," "Late Late Show" host James Corden quipped. "Not the moneymaker, and not the babymaker."

Gronkowski told Corden that getting tackled in the NFL is no big deal because "I've been getting hit my whole life."

As for how Gronkowski plans to treat younger brother Glenn now that he's joined the Buffalo Bills, Rob suggested he won't ask his New England Patriots teammates to go easy on him.

Blows to the face and crotch "are both penalties out on the field," Gronkowski said, "but they can give him a little dig."
