Those the rhymes my grandpa used when we played cribbage. If there are rhymes for higher scores, I don\'t remember them. I lived in Canada at the time of learning the game, and I\'m 41.
If it makes you feel any better, though, I played my first game in ages a few weeks back, here in Tennessee, with a friend in her early 30s who had also played the game a lot in her youth.
Euchre, Rook and Wizard are games that seem very regional to me. Euchre is much more popular in the northern US and Canada than in the southern US. I used to work in a game store and people would ask me about the game Wizard (also big in Canada) and I\'d compare it to Euchre and they would have not even ever heard the name. I later learned that Rook would be a better comparison for them, as it\'s very popular here in the south, but was one I was unfamiliar with.
