Miles and I don't play cribbage any more since we invented doublage, which is kind of "double cribbage." Instead of dealing six cards and putting two in the crib to create two four-card hands and one four-card crib, play with two decks (104 cards), deal nine cards, and put three in the crib to create two six-card hands and one six-card crib. All other rules are the same, except that we go four times around the board rather than twice. (You need 241 points to win instead of 121.)
The highest possible hand is 112 points (seven fives); the next highest is 91 (jack, six fives, nibs; the equivalent of the 29-point hand in cribbage). The highest-scoring hand we have had is a 58-point hand that Miles had once (when he needed only 20 to go out); my best hand was thus ruined: a 50-point hand that I did not get to peg because of his having won already!
The funniest thing to have was double nibs, when I had two jacks of the suit of the card that was cut. Finally, in doublage it is nearly impossible to get a dry hand or crib.
