Me: What does a milkman bring?

Grandboy: Milk

Me: What does a mailman bring?

Grandboy: Mail

Me: What does a fireman bring?

Grandboy: Um

Grandboy: Fire supplies!

Me: What kind of supplies?

Grandboy: Um. Hmm. Ah! Water!

Me: So we should call him a ‘waterman’.

Grandboy: Yes! We’ll call the waterman in case of fire, because the fireman will bring fire and burn down the house!
