Noah Gragson fools Kyle Busch at his Fan Day

Kyle Busch's Fan Day on Friday saw one special guest line up for an autograph: Kyle Busch Motorsports driver Noah Gragson approached Busch hunched over and wearing a yellow No. 18 jacket, hat and sunglasses. For a moment, "Rowdy" thought he was just another fan, as he signed the No. 51 die cast. One gesture after that, though, may have blown his cover. Watch the entire encounter below.
