The photoshop mavericks over at Something Awful based last week's picture alterations on a shopping cart safety warning sign. You know, those little warning "seats" that you place kids in and they tell you what not to do while using them? Yeah, those ones. Anyhoo, one example of some great photoshopping is the Portal themed one you see above in all its cake glory. There's another Portal one after the break jump and even a BioShock themed one too. All are great photoshops and are based on themes that made us laugh. And before you ask (because we know you will), we say yes. Yes we would shop at a store that had these seats in their carts even if they were that nastified and dirty. That's just how we roll.
