eres más tonto que abundio 21
There are four or five possible origins of this saying; from the martyr San Abundio, until an Admiral of the 18th century, who crashed his boat to face off against U.S. troops. The sense that name farmer takes advantage to disseminate stories aimed to show the degree of stupidity, or lack of intelligence of a person. Depending on the area of Spain, it will be that Abundio was so silly that for harvesting the vineyards, was grapes for dessert; or who sold the car to buy petrol.
