Rafael and Josh C I think had the funniest but most fitting decoy in the stilt walking challenge. I have to admit it was bad, but it was hilarious. I think Tim was worried it was serious, but both of them did do decent enough clothes that this was obvious more of a joke thank serious work. Plus, seeing a couple of awful outfits in the mix there... I was pleasantly surprised it blended in anyway.
I think Tim was crying because he hasn't really been given this type of respect I think. That said, it's obvious he's on a "lite" mode due to his personal opinions of the judges or something in previous seasons. But, I personally think it was nice to see this side of Tim.
Do agree with him on the glue issue - too much glue, and it should be a huge alert it's overused when one contestant - Oliver - actually tried to cut corners in fabricating something at all by gluing the outfit onto the model. Don't blame him for wanting to ban glue as a form of stitching; however, the fastener issue depends on what they're actually using before I'd say ban any sewing the clothes onto the models. Some things, such as say the newspaper challenge, you can't really have fasteners so you may have to "Sew" in your models.
