Freedom of choice

Little Dog was deciding who had to take him to the downstairs bathroom since the upstairs bathroom is currently out of commission. 
"Eeenie, meenie, minee, mo!" he said, pointing to a place between me and Mr. Dog.
"Who was that, mom or me?" asked Mr. Dog.
"You!  You're mo!"
"Really?  I'm mo?" says Mr. Dog.
"Yep.  I totally moed you."
And off they went.
