What are the odds?

What are the odds of someone having 4 pocket pairs in 9 hands and hitting a set with all of them? I only ask because the fourth time Denise hit a set in the Fitz 270 game last night it was against me to crack my Aces (The first time I voluntarily put chips in the pot!). Admittedly she did not play one of the pocket pairs but a reliable witness saw them. Should I have laid them down that early in the tournament when she moved in on a Q62 flop with two spades? I had the Ace of spades. I dunno, tough one. I called pretty quick, moving in looked like AQ or even the second nut flush draw. As it was I was drawing to runner runner flush as two other people had an Ace. It was also a 3 way pot so there was a lot in the middle for her to take down if no-one had hit. I would have had 3800 from 5000 starting had I folded and blinds had just gne up to 50/100 so I would have been in good shape. Darn those rockets...

Citywest tonight, I am going to win this one :)
