Thanks to Dawn for this. She says:
I'm on a horse, psamp! – Not the Same as a Boat
Incredibly, this is far from the first goat-on-a-mini-pony featured on PSAMP. Just this past May we had a video of a goat riding a mini pony in Newfoundland and then getting bucked off. That one had awesome value as a series of funny events captured on video, but I'll accept any pictures with tired "I'm on a Boat" references as long as there's a mini pony with or without a goat. I'm easy.
