Oldie but goodie
An old Italian gentlemen lived all alone in New Jersey. He wanted to plant his annual tomato garden, but it was very difficult work as the grand was very hard.
His only son, Vincent, who used to help him was in prison. The only man wrote a letter to his son and described his predictament: Dear Vincent, I am feeling pretty sad because it looks like I won't be able to plant my tomato garden this year. I'm just too old to be digging up a garden plot. I know if you were here my troubles would be over. I know you would have been happy to dig the plot for me, like in the old days. Love, Papa.
A few days later, he received a letter from his son: Dear Papa, don't dig up that garden. That's where the bodies are buried. Love, Vinnie.
The next morning, FBI agents and local police arrived and dug up the entire area without finding any bodies. They apologized to the old man and left.
That same day, the old man received another letter from his son: Dear Papa, go ahead and plant tomatoes now. That's the best I could do under the circumstances. Love, Vinnie.
