what are the odds?

[Pocket Trips]

Just had a 5 card draw hand that was unbelievable...I was dealt an ace high flush in a PL game and raised a maniac all in .. I of course stood pat and the maniac drew 3 so i figured I was in great shape... WRONG!!!!

This maniac drew 3 after going all-in and drew 4 god damn aces!!!!!!!!!!

what are the odds on actually drawing 4 aces in a 5 handed 5 card draw game.. 1st assuming you have a pair to start with and 2nd if you have just one ace... I'm too pissd off to do this math right now
