itty bitty cows

We were all making a recipe that involved canned milk. Many of the children had never seen milk in a can before. As we were investigating, poking and prodding at all the ingredients before we began I overheard a discussion between the preschooler.

"I never-ed saw that a-before! Milk in a little itty-bitty can! He-He!" Paulie was holding up the can and shaking it.
"It's called condensed milk." I explained.
"OOoooh. Is it made from condensed cows, Ms Barbra?" One child inquired.
"Uh....no. No condensed cows." I said trying not to laugh.
"Cool." Said one child grabbing the can to inspect it further.
"So...Ms. Bar-ba? Nina asked.
"Yes?"
"How do they get the cows to sit down on these itty-bitty cans?"
