Former NASCAR driver Landon Cassill recently took to social media with humorous advice for Xfinity Series driver Connor Zilisch on victory celebrations. In the wake of Zilisch's fall off his #88 car after winning at Watkins Glen, Cassill suggested a new idea to celebrate a win.An X user with the handle fugustra1 posted of a person literally jumping inside the hood of a red car and doing burnouts despite not being behind the wheel. The user added a message with the video, writing:"I don’t think car manufacturers know their cars can do that...😂"Cassill saw the video and reposted it with a message for Zilisch, who's a nine-time winner in the Xfinity Series. The former Cup Series driver hilariously gave Zilisch the idea of doing the same thing as a win celebration."New victory celebration idea @ConnorZilisch," he wrote.Connor Zilisch then responded to Cassill, making fun of himself for falling off the car after winning at Watkins Glen. The JR Motorsports driver jokingly said that because he can't even stand on his car without falling, doing burnouts from inside the hood isn't a great option."I can’t even stand on a window let alone do donuts from the hood," Connor Zilisch wrote.Zilisch scored his sixth victory of the 2025 NASCAR Xfinity Series season back at Watkins Glen on Aug. 9. As he climbed out of his car in victory lane, Zilisch slipped off the car and landed violently on the ground. He was taken to the infield care center following the incident and was later diagnosed with a broken collarbone.Due to the injury, Connor Zilisch was forced to sit out the Cup Series race at Watkins Glen the following day.
