Traffic was stopped in “Yellowstone National Park” this week to let a bison safely cross the road.
But one man decided to get out and start taunting the animal, running up to it and flexing.
What he apparently didn’t know is that this is the bison mating season.
The animal bellowed and charged to show dominance.
The encounter ended without anybody getting hurt. But park officials warn that kind of behavior is reckless and illegal.
They also point out that bison can run three times faster than most people.
