WWE's merchandise department is a well-oiled machine these days, churning out a steady supply of (often bland) t-shirts for their superstars. It seems that not a week goes by that we don't see a new John Cena or Daniel Bryan design. Hell, even the NXT superstars have their own t-shirts these days, available to buy on the company's website. Back in the Attitude Era, however, there was some apparel produced by the company that it's hard to believe anyone bought, but buy it they did. The Rock's 'Poontang Pie', Chyna's 'Va-Chyna' and BIlly Gunn's 'Mr. Ass' shirts are all just absolutely awful and something most wrestling fans wouldn't be caught dead wearing. One of the worst t-shirts to come out during the era was this Rikishi monstrosity. First of all, who would walk around wearing something that said 'Back Dat Ass Up!' on the front of it? Idiots, probably. Secondly, who would walk around wearing something with a picture of a large samoan man's ass on the back of it? Just awful. We doubt WWE will be selling these relics in the run-up to the big man's Hall of Fame induction.
