odds of KK running up vs. AA in the same hand?

[whiskeytown]

Just a quick stat. question...a detailed explaination of how someone reasons this out would be super.

We know from common knowledge that you'll get AA only 1-210 times at a table. The same goes for KK, of course.

What are the odds on say, a 9 or 10 handed table, of a player like us getting KK and end up playing against AA on the same hand. This is preflop of course, and in NL, probably the kind of hand where ALL the chips go in the middle of the pot...LOL

I've just felt it's been happening a lot lately to me. Statistically, it's within reason to happen every few games, esp. in a tourney. Just curious how many times I'll see it when I get KK.
