The Painted Porch
Being a bit down on his luck, a man goes door-to-door looking for work. Finally at one very nice looking house a compassionate woman offers the man work painting the porch out back.
She figures it will take about two hours and offers the man $20 to do the job. He agrees. She gives him a gallon of green paint and a brush and he goes behind the house to work.
Barely a half hour later he knocks on the door, explains that he has finished the work and would like to get paid.
The woman expresses surprise that he has finished so quickly and wonders if he did a good job. The man assures her that he did a wonderful job.
“But” he says, “I have to tell you, it really isn’t a Porch, it’s a Ferrari !”
