Old Mr. Cohen brings his son into the business, Cohen's Nails, in the hopes that one day his son will take over. As time passes Mr. Cohen starts getting more and more worried, no matter what department the son is put into he cannot get anything right and is continuously mucking everything up. After talking to some of his friends and business partners Mr Cohen decides that maybe the reason his son is doing so badly is because he is supervising him too closely so he decides to give him a task to do where the son is in charge. The task is handle the new advertising campaign. The son is delighted and starts working really hard. The father is delighted also as it looks like the idea will work. Time passes and the son comes to Mr Cohen and takes him out to see the new billboard. It is in a fantastic position, on the highway, thousands of cars passing it daily, but Cohen almost has a heart attack when he sees it. There is a picture of Jesus hanging on the cross, with the caption "Even back then they used Cohen's nails." After explaining to his son that many customers are not Jewish and would find this offensive, the son promises to change the sign. Another frantic month of activity and the son comes back to him and drives him out to see the sign. The new sign has a picture of Jesus lying in a bundle at the bottom of the cross with the caption "If they had used Cohen's nails, this would not have happened!"
