Here’s a textbook case of immediate regret.

When Nick Bull decided to take Shamrock, a retired racehorse, out for a light trot, he didn’t expect to be holding on for dear life. Unfortunately for Nick, ol’ Sham decided to briefly relive the glory days.

“Whoaaa, Shamrock. Oh, Jesus Christ. Sham, Sham, whoaaaaaa. Whoa, Sham. Oh dear. Sham. Whoa. Whoa, Shamrock. Whooaaaaa,” is about as much as rider Nick Bull could scream as he went for a ride he won’t soon forget.
