As noted earlier, The Rock recently posted a photo of his new "Boots To Asses" t-shirt and claimed it was the best selling WWE t-shirt on WWEShop.com. CM Punk responded by tweeting the following: "The Rock comes up with another lie..Claiming his shirt is the most sold in WWE. We all know it's the @CMPunk T-Shirt, that's most sold."
The Rock posted a follow-up over the weekend, writing that it's official – his Boots To Asses t-shirt has been WWE's #1 selling item since November 14th. WWE's official Twitter even re-tweeted what Rock said.
CM Punk has since replied, "::sigh:: you live in a fantasy world. Numbers don't lie"
I don't have any official numbers, but The Rock's original tweet was about his shirt being the top-seller on WWEShop.com. My guess would be that he is correct, and that his shirt is the best selling on the website while Punk's shirt is likely the best-selling overall, since you would assume Punk's shirts sell more at arena shows with him wrestling.
