Milk as an action verb

My three year old is fascinated by nursing, and has transformed "milk" into a verb. In a game he's playing with my mother, he just told her he would be "Loop Skywalker" and for her role...well, I'll use his words:

"Yer the mom, you can milk!"

Light saber versus milk, it's an epic contest.

Follow-up:
Having just been given the role of Dad, I asked the boy:

Me: What do dads do?
3 year old: Work.
Me: What do moms do?
3 year old: Play.

I knew I had the better deal.
