A Bad Omen?

I sit down at a four card poker table; my first three hands all have 6-6-6 in them. Eerie, huh? Wonder what the odds of that happening are. The rest of my session was a little less weird. I get a straight flush, next hand, the guy to my left gets a straight flush. A few hands after that, the same guy gets another straight flush! I went to 3 Card, won some more money there, and got the hell out.
