Bison, meet jackass.
A bozo was captured on cellphone video taunting a large bison in Yellowstone National Park this week.
In the less-than-1-minute-long online clip taken Tuesday by bystander Lindsey Jones, a shorts-wearing man beating on his chest is seen approaching the ungulate on the two-way road in Hayden Valley.
The bison — which can weigh up to 2,000 pounds and stand 6 feet tall — is having none of it and promptly charges at the man, video posted to YouTube by KRTV News shows.
“Oh God, I can’t watch,” a person can be heard saying in the video as the bison charges the man for a second time.
