Under the wagon
A farm boy accidentally overturned his wagonload of wheat on the road. The farmer that lived nearby came to investigate.
'Hey, Willis,' he called out, 'forget your troubles for a while and come and have dinner with us. Then I'll help you overturn the wagon.'
'That's very nice of you,' Willis answered, 'but I don't think Dad would like me to.'
'Aw, come on, son!' the farmer insisted.
'Well, OK,' the boy finally agreed, 'but Dad won't like it.'
After a hearty dinner, Willis thanked the host. 'I feel a lot better now, but I know Dad's going to be real upset.'
'Don't be silly!' said the neighbor. 'By the way, where is he?'
'Under the wagon,' replied Willis.
