Every person’s definition of “things that make you feel all’s right with the world” differs, but Foot Locker’s idea, in a new ad with Kyrie Irving, is pretty close.

Brett Favre muses that, “a man’s got to know when to walk away,” and Dennis Rodman buys a one-way ticket to North Korea. But Mike Tyson steals the show as he gently, innocently rings Evander Holyfield’s doorbell and … returns the portion of Holyfield’s ear that he bit off in a 1997 fight.

Never mind that it was sewn back on after the bout. This is gold.

“I kept that in formaldehyde.”
