Little Johnny... Don't laugh! :D

Little Johnny comes downstairs crying. His mother asked, “What’s the matter now?”
“Dad was hanging pictures, and just hit his thumb with hammer,” said little Johnny through his tears. “That’s not so serious,” soothed his mother. “I know you are upset, but a big boy like you shouldn’t cry at something like that. Why didn’t you just laugh?
“I did!” sobbed Johnny.
