"Can we go to Grandpa's farm today?" asked Joe.
"Why do you want to go there?" asked Mom. "We were just there last week."
"I know," said Joe. "But I was wishing I could have a chocolate milkshake."
Joe's mom gave him a funny look. "What do milkshakes have to do with Grandpa's farm?" she asked.
"Grandpa milks his cows two times a day, right?"
"The cows are brown, right?" asked Joe.
"Yessss," said Mom slowly.
