During a round of the American Celebrity Golf Championship, ?Patrick Mahomes? had some fun with the fans in Lake Tahoe.

At one point, a patron told the Kansas City Chiefs signal-caller to "watch out for ?Justin Herbert? next year."

Mahomes quipped back, smirking: "I'll see it when I believe it."

As with most things uttered from the half-a-billion-dollar quarterback's mouth, the clip went viral, with it appearing Mahomes took a shot at his AFC West rival and 2020 Offensive Rookie of the Year winner.

(We'll set aside, for now, Mahomes accidentally (?) flipping the phrase. Perhaps he just subscribes to The Santa Clause ideology wherein, "Seeing isn't believing. Believing is seeing." Deep stuff, Patrick.)
