I just remembered that I used to play Blackjack with the DOG!!
I used to go to the casino on a regular basis. But sometimes I'd be at home, and bored, and the dog would want to hang out (yes I have cats now -- this is the dog that my ex husband has now, but we used to share the dog). So, I'd deal us up some cards, and if she just looked at me, I'd take that to mean "stand", and if she pawed, I took that to mean "hit me".
One time Scott came home and was like "Are you playing blackjack with the dog?" and I was like "Duh!"
I should teach the cats how to play craps.
