Grandpa's Birthday Party

A mother was taking her two young ones to grandpa’s birthday party. The two kids were whispering in the back seat. One of the children said, "You can’t have a birthday party without a birthday cake." The other child said, "Yup, that’s right! No cake no party!" "What makes you two think there won’t be a birthday cake?" asked the mother. "Are you kidding mom, Grandpa's going to need a garden hose to put that fire out."
