Anyone figure out the odds on this

[als2430]

Just wondering, I picked up a royal flush in a hold em poker game. Yes thats special, but this came against a 4 of a kind. Can anyone figure out the odds of a royale and a 4 of a kind coming on the same hold em hand, with only 4 community cards turned over.

That's a tall order. You want the odds figured in of whether players have the correct hole cards to get these hands too? How about the chances of any two given players at a table with X players?

P.S. I just saw four-of-a-kind beaten by a straight flush at the Bellagio in Las Vegas a couple days ago (Ya, no jackpot there, ouchie!), so I'm assuming it happens all the time
