Why gambling is dangerous

I just asked Adrian if he would help me with the 3 kids' bathtimes and hair washes. 

He said "Sure." 

I said, "Unless you want to do rock-paper-scissors for triple or nothing." To which he said he did. 

So, we did rock-paper-scissors 4 times and picked the same thing each time. And then the 5th time he picked paper and I picked scissors.

I am now sitting on the couch watching TV and he's stuck with the 3 ankle biters whining in the bathroom. I actually feel bad for him and am considering going to help.
