Pa won't like it..

A farm boy accidentally overturned his wagonload of corn. The farmer
who lived nearby heard the noise and yelled over to the boy, "Hey
Willis, forget your troubles. Come in and visit with us. I'll help you
get the wagon up later."

"That's mighty nice of you," Willis answered, "but I don't think Pa would like me to."
"Aw come on boy," the farmer insisted.

"Well okay," the boy finally agreed, and added, "but Pa won't like it."

After a hearty dinner, Willis thanked his host. "I feel a lot better now, but I know Pa is going to be real upset."
"Don't be foolish!" the neighbor said with a smile. "By the way, where is he?"
"Under the wagon."
