On Tuesday's What's Trending segment, Josh had a story about Jon Stewart trending on Twitter because he made a comment about Dasani bottled water and Arby's. Stewart famously does not like Arby's (doesn't make sense) so he clearly does not like Dasani as well. Bob and Gitter were of the opinion of water is just water. Josh said Dasani is trash so we decided to have Josh try a bunch of bottled water to see if he could identify the Dasani. He samples seven different bottles, including Dasani, with the hopes of being able to pick it out. (Photo/Getty Images)
