Maniacs, and more maniacs (low/no content)

Two nights ago, Ultimate, 0.5/1, 6-max, I joined a table where three players were capping every hand pre-flop, and capping every street after the flop. It was an incredible thing to see. In theory I could have made a lot of money, but they effectively made the game more expensive than I can play. It was more like plugging tokens in a slot machine than playing poker.
Last night, Ulitmate, 1/2, 6-max, one player was 100/60 and another 75/30, but both were calling stations after the flop with total garbage. I made a good chunk of change for me (30BB in 45 minutes). The 100/60 player didn't fold a single hand pre-flop for four cycles. When he finally folded one, I commented "x actually folded a hand preflop", he just said "I'm on tilt" and kept throwing away his money.

UB has a reputation for fairly tight games, but these guys were nuts. At my fishy-est I never played like that. What the heck are these people thinking?
