Did you see the one where they put 3 or 4 dead pigs in a car then sealed it up and stored the car for 6 months? They wanted to see if they could clean it sufficiently to resell it !? Really gross! My favorite episode was the one where they shot different things out of a cannon-I don't remember why they did it though. I guess just because they could.
I think I've seen most of the episodes - my husband saves them on the DVR and I usually get sucked into them
I love how much fun they have and it is really interesting. Adam's shirts are always funny!
My favorite would be the one where they were trying to prove a stressed out/distracted driver would waste more gas while driving so they made sure the driver really needed to use the bathroom, made the seats uncomfortable, put sticky stuff on the steering wheel and turned a live rat loose in the car!
my favorite one was when they did the airplane on a conveyor belt, would it take off... There have been debates raging for years all over the internet that go tens of thousands of posts.
