Duuuude, they DO stink, there are few things worse than getting stuck behind a fatty getting off the plane.  As soon as they get up, all those farts leech out of their ass.  It actually reminds me of an open sewer.  Then you have to wait, and wait for the tub to squeeze to to front of the oppression tube.  The good part is hitting the jet way and flying by, you will catch the smell again when you go by Cinnabon though
