I taught my step son to play when he was about eight years old. In about his second week of learning, the little brat got a 29 hand. He had to call his grandfather, also an avid player, to tell him the news!
I've been playing cribbage for over 50 years, and have probably only gotten three or four of them.
That reminds me of being dealt a Royal Flush at about the same age, in a friendly poker game with my dad, uncle and grandfather.
