"oh man, we went to Mexico. And we thought it'd be fun to go to a show, and it's a woman fucking a horse. We get there, and we think it's gonna be awesome, and it's not as cool as it sounds like it would be, man. It's kinda gross. You think a woman fucking a horse, and you get there, and it's a woman fucking a horse. It was really giving it to her. And you know what? to be honest I felt bad for her, we all just felt bad for her. Kinda felt bad for the horse." pony girl, lol.
