2 weeks ago in a live 4/8 game I was playing, 2 Royals and 2 straight flushes in about 4 hours ( 110ish hands ) at the table.
Holy Cow. Will you teach me how to play like that?

Odds of having a royal on a given hand:
[4 * C(47,2)]/C(52,7) = 4324/133784560 = .00323%
Odds of having exactly two in 1200 hands:
=BINOMDIST(2,1200,4324/133784560,FALSE) = 0.0722959%
Correct me if I'm wrong, it's been known to happen =).

...and I believe two or more is extremely close at:
=BINOMDIST(1198,1200,133780236/133784560,TRUE) = 0.0732381%

It wasn't me, just at the table. So it's not quite as cool.
