Rob Gronkowski appears to thoroughly enjoy himself at Daytona 500

Rob Gronkowski appears to thoroughly enjoy himself at Daytona 500

New England Patriots tight end Rob Gronkowski attended the Dayton 500 in true Gronkowski form.

He appeared to be there promoting Monster Energy drink, and was therefore hanging with the Monster Girls, who were also promoting the drink. Gronkowski's herniated disc injury, which required surgery in December 2016, does not seem to be slowing him down as he gets warmed up for the Summer of Gronk.

During the race coverage on FOX Sports, Gronk delivered a speed limit joke, which is sure to make the 13-year-old in you chuckle. (You can watch it here.)
