Advertising campaign of a nail company

There was a wealthy Jew who owned a nail company. His only son had just graduated from college and the father wanted to get him involved in the company. So he placed his son in charge of the new advertising campaign. He told him that he would have no supervision and that any and all resources he need would be at his disposal. The son was elated and immediately set off to make his father proud.
Four weeks later the son proudly proclaimed, "I have finished!" He took his father out to examine the first product of the new campaign: a billboard portraying Christ on a cross with the caption, "Even Then They Used Goldberg Nails".
The father explained to the son that they couldn't portray Christ on a cross as it might offend their Christian clients. Dejected, the son said that he would fix the problem and report back to his father.
One week later the son took his father to see the billboard. Christ was no longer on the cross; he was lying at the base of the cross and the caption read, "This Wouldn't Happen With Goldberg Nails".
