I actually came across these t-shirts a while back in a t-shirt store in Shibuya. That store sold t-shirts from many designers but these were two of the funniest there. The first one is called Drunken Donuts which is a spoof of Dunkin’ Donuts of course. One bite makes you drunken’ happy! You’ll be shocked by the adult taste.
The other is a great M&Ms spoof called S&M’s featuring a fishnet stocking wearing, whip lashing, candy dominatrix. It’s a great one color design. Click the thumbnails below for a better view. You can check out the (pretty limited) selection of shirts online at Little Pirates. The site is in Japanese and it doesn’t look like they ship overseas either though. The shirts a little pricey too at 3570 yen.
