Yea, playing dumb is a blast especially with a bunch of whiners and complainers. One of my favorites is asking how much rebuys are after I loose a chuck of my stack in a regualar STG.
I do hate players that berate and insult the other players especially the fish, telling them they suck or to rebuy again. I ususlly make a note and try to crush these jerks when I get the chance. I figure we were all fish at one time or the other and why bite the hand that feeds you.
