Actually I did see this some years back...three guys on a business trip flying DL from DFW-BOS on a 757. Two of us were upgraded to F...we wandered back halfway through the flight to check on our "unlucky" co-worker only to find him sandwiched in a middle seat between two stunning, 20-something, lycra-clad twin sister aerobic instructors. He advised us later that they'd asked if he wanted to move to the aisle and he declined.
