Artist’s description from DA:

Why who’s this extra-large bundle of charm and charisma?  It’s Aloysius Horatio Docboy Gladmane, showpony extraordinaire!  He runs an intermittently-traveling Equine Oddities show out of Las Pegasus, and everywhere he goes he brings the party with him. Bizerbit is in charge of the Equine Oddities (read: freak show) arc, so I’m only going to skim it.  Gladmane hires (sometimes purchases) the strange and unusual denizens of Equestria and beyond, affording them stardom and sweet, sweet dignity.  This isn’t 100% due to him being a great big teddy bear; Gladmane and his performers are each other’s meal ticket, and the system works swimmingly as long as nocreature rocks the boat.

Gladmane himself?  What a guy, y’all!  He’s got an easy drawl, a mountainous coif and more illegitimate kids than you can shake a paternity test at.  He’s allegedly got more funky after-hours liaisons under his belt than even card-carrying hypocrites Hoity and Franzie down there.  Maybe you’ve met a few of Gladmane’s chubby foals.  He sure doesn’t know them, but we might!

Truly between Gladmane and Hoity it’s amazing that anypony else in Equestria manages to keep ahold of any hair product at all.  Hide your conditioner, hide your Dapper Dan.
