If you're wondering what would make a man jump on a police vehicle right in front of them, Fresno, California police officers would like to know, too.
23-year-old Adolfo Lopez was already on top of the SUV when an officer spotted him.
Several officers tried to talk him down for about a half hour, but he wouldn't budge.
At one point, he did jumping jacks on the roof and smashed the lights with his foot.
Eventually, officers physically took him down, but not before he caused a lot of damage.
Lopez was taken to a hospital for evaluation.
