double quads
 

The other day i flopped two sets of 10's and 4's playing a home game. I turned quad 4's and improved to quad 10's on the river. It wasn't high stakes but fortunately someone else had flopped a set of eights and i got some decent action, and more importantly for me the pleasure of showing the hand!

What i want to know is whether anyone knows the odds of making double quads?!
