Apparently a favorite tourist pastime in Thailand is croc baiting (or at least it is for the guys in this video). They appear to be on some kind of raised hotel bridge area above water. One of the guy has a bamboo fishing pole with a piece of chicken tied to the end of it. There are various crocodiles swimming around below them snapping at the piece of chicken or whatever it is. The crocs make some wild grabs for the meat but keep missing. Finally they put the meat really close to the nose of one of the huge crocs and he grabs it in less than a second before the fisherman guy can react.
