I had 67 of diamonds in late position. Medium raise by guy on the button (trying to steal) and about 4 callers. Flop comes 5s 8d 4d, giving me the nut straight with a flush and straigh-flush draw. Check around to the guy on the button. He comes in with a moderate bet (about 3x blinds). I call as does 1 guy in front of me. the river comes the 5c. Check, Check, guy on the button makes a huge bet. The only other guy folds, I put him on trip 5\'s. I slow call. Turn comes 5d giving him four 5\'s and me a straight-flush to the 8. He goes all in and I call. I love being on this end of the bad beat.
