Jeff Beacher: Horsing Around After Kendall's Mustang Mix-up!

Just days after Kendall Jenner psyched out the internet with her stallion switch-a-roo -- showman Jeff Beacher set his blinders on the pony picture for his latest celebrity stunt!

Beacher -- who recently lost 160 pounds -- bared his bronco for this incredible bareback photo to add to his impressive collection of celebrity spoofs.

With parody pics of Justin Bieber, Kim Kardashian, Miley Cyrus and David Beckham in his prank portfolio ... we'd say Kendall is in pretty good company!

What a stud.
