Horseboy
"Horseboy" is a man with a horse head who has shown up in various places across the Internet, including places like standing on the side of the road in Scotland in Google Streetview.
NSFW Connection
Every so often, Brian will play an animated GIF of a man in a sportcoat and a horse mask dancing.
Dragon*Con
In Debit Daddy, Patrick Delahanty included Horseboy in an Adobeshop prediction for what Brian and Justin would encounter at Dragon*Con.
During the live show at Dragon*Con, Patrick put on a horse mask and performed the dance to defeat Debit Daddy and an alien in battle. Of Horseboy, Brian said, "Look at my horse. My horse is amazing." Adding, "It may in fact be a moth." Horseboy and the alien shared a tender moment and made out in front of the audience, which disgusted Veronica Belmont and sent Brian and Justin into fits of uncontrollable laughter.
Following the live show, Justin put the mask on and danced.
Later that evening, Chad borrowed Patrick's coat in the middle of the Marriott, put the mask on, and started dancing. It was only seconds before a stranger asked for his photo. (The photo has not surfaced.)
Post-Dragon*Con
After Dragon*Con, Tony edited clips from that episode into Scott Johnson vs. The World when Brian and Justin recapped what had happened. Horseboy later appeared in part of the after show for You've Been Rookered complete with headset and microphone.
In Eight Equals Equals Equals Dee, Horseboy was declared to be the deity for Bonearth.
Presidential Campaign
In Betterlection Day, Horseboy was elected President of Bonearth and the Betternet as a third-party candidate and part of a joint ticket with Fapper. One of the ads in the episode featured Horseboy in front of an American flag citing his experience defeating aliens, a reference to Dragon*Con: Con of a Dragon.
Another political ad featured part of the "Justin Danes as horseboy" video and claimed that Justin himself was Horseboy. Although Justin has impersonated Horseboy and attempted to copy the dance, Justin is not Horseboy.
