The Jay Rosen and the Toasted Bagel incident occured when Adam and Liam went snowboarding back in 2001. Prior to leaving for the mountain, Jay Rosen had toasted a bagel and wrapped it in tinfoil. Jay asked Liam and Adam (who were sitting in the back of the truck due to limited seating) if they wanted one of his toasted bagels. Liam just stared with a weird expression on his face. Jay waited for a response from Liam, but when he continued to just stare at him, he threw the bagel at Liam and slammed the back of the truck shut.
This was the same day that Adam and Liam had their snowboards stolen.
