I had it once. It was As and Js in my hand. Flop was Qs 10D Ks. Turn was 10H and River was 10S. Somone else had 10C and KC, he went all in on the turn and I was happy to take his chips (but it was a small game, 10 bucks buy in for 6 people). He was happy to see the 10S for about two seconds before he realized I had the royal flush.
