Tony Rock says his brother Chris kills the gift-giving game every Christmas … and, even makes up for the subpar presents their less successful brothers give them.

We caught up with the comedian at LAX Wednesday … and, we had to ask him how Christmas works between the seven Rock siblings — especially when it comes time to tear off the wrapping paper.

Tony says expectations are different for each Rock sibling — joking that the family expects “sh***ier gifts from the brothers who aren’t famous.”

Chris gives the best presents, Tony says … even making up for some of the less desirable gifts he gets from his other siblings.

Tony says there’s definitely a pecking order … one he’s still pretty high up on — saying he gives from the heart, but also spends a little cash as well.

Tony also tells us about the best gift he’s ever received … watch the clip until the end to hear all about it.

Chris and Tony had five other siblings — four brothers and a sister — one of whom passed away in 2006. While their younger brother, Jordan, followed their footsteps into comedy, the rest have largely stayed out of the public eye.
