"Whoah, whoah, whoah... Sham, walk... woah... Shamrock!... No, Sham for FUCK'S SAKE!"
These are just some of the gloriously panicked sounds made by the man filming the video above, as he desperately attempts to stop his retired racehorse Shamrock from reliving his glory days on the track.
"Shamrock is a retired racehorse," wrote rider Nick Bull in the YouTube description. "On this day, he forgot he was retired, or that I'm not that experienced a rider and decided to take me for the ride of my life."
No prizes for guessing how the video ends.
