With icy water making for difficult fishing and navigating, tensions were high on "Deadliest Catch" (Tue., 9 p.m. ET on Discovery). The crew started shouted at each other, and one crewman nearly got himself kicked off the boat when he called the rest of the crew "lame."

These guys may be a lot of things, but lame isn't one of them. They bravely take on some of the most dangerous working conditions on the high seas, and do so with high spirits, a wild dedication to their work, and a professionalism that most employers would envy.

With the icy waters, the work was even more dangerous than usual. The fisherman struggled to break through the ice to get any fishing done, while the captains had to work extra hard to avoid getting their ships stuck in the ice.

The dangers continue on "Deadliest Catch," Tuesdays at 9 p.m. ET on Discovery.
