I'm sorry, but there's a guy at my table who makes me question the whole concept.

-he plays every hand. this is not an exaggeration. he limps every single hand and calls any raise before first draw. I have seen him call a raise and then draw 5.
-he will call behind with a Q after the third draw. that is not an exaggeration; he paid money to show a Q8
-after salivating over his asshataments, I finally got into a big hand with him and he showed number one. whatev.

last, but not least:
instand hand history indicates he drags almost 40% of the pots, and he is up 20 big bets in the twenty minutes i've been sitting.
