How far should I have gone wtih my pocket 6's?

ok, so i know i made the right fold, BUT,

Do you guys have a favorite hand that you always play with and do well with? maybe a bit superstitious? Kinda like how Doyle Brunson like to play 10-2, etc....

Here's the reason I ask, last week, played on Absolute Poker on friday and saturday night, on friday, in a ring game, with pocket 6's, i flopped quads. Funny thing is, it happened again the very next night.

Just curious, that's all...
