Are you ready for drama, scheming, and Heidi Klum‘s legs? We hope so because Project Runway, the design show that everyone loves to hate is in its tenth season–and it premieres tonight. Hard to believe that it’s been 10 seasons, right? It seems like only yesterday that we were asking ourselves about Tim, “Who IS that dapper man with the amazing vocabulary?!” And now, no Thursday night is complete without him.

While we love the personalities on the show (Hi, Michael!), part of the show’s ridiculousness involves the tasks that the designers are given. As if it wasn’t crazy enough to set unrealistic time deadlines and let sleep deprived people run around frenetically with scissors, the producers complicate things even further with their “challenges.” From the now infamous grocery store challenge to designing haute couture from pet store wares, Project Runway takes the edict “Don’t bore Nina!” very seriously. And viewers could not possibly be expected to sit and watch a show about, you know, clothes made out of regular fabrics, for an entire hour.

So to welcome PR back into our living rooms tonight, we took a look back at the silliest challenges that the show has dished up. Click through and take a walk down the trash bag aisle with us as we relive them all.
