Doughnuts or Ice Cream

Mom: (after a particularly trying day) Ok, if you guys will clean up, I'll get you either ice cream or a doughnut.
Asher: Um, can we get both?
Mom: No way!
Asher: Why not?
Mom: Because that's way too much sugar...
Asher pauses to think
Asher: Mom, which has more sugar a doughnut or ice cream?
Mom: Asher, I have no idea.
Asher: I'm going to get ice cream because I bet it has waaay more sugar.
