Who said Mexicans were dumb?

An old man lived alone in New Mexico.  He wanted to spade his chili garden, but it was very hard work.  His only son, Francisco, who used to help him, was in prison.  The old man wrote a letter to his son and described his predicament:

Oye Francisco,

I feeling pretty bad cuz I do not think I will be able to plant my chili gardenz this year.  I just getting too viejo to dig a garden, but if you waz here, all mi problemas wood be over.  I know you wood dig the plot for me.

Siempre,
tu Papi

A few days later he received a letter from his son:

Dear Papi,

Por favor, no! Don't dig up the garden! That's where I buried the BODIES!

Love,
Francisco

At 4 a.m. the next morning, FBI agents and local police showed up 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 Papi,

Go ahead and plant the chilis now. It’s the best I could do.

Love,
Francisco
