Farmer, 74, Grows Cannabis Crop by Mistake

""An elderly Bavarian farmer who said he had intended to grow sunflowers planted a field of 1,000 cannabis plants by mistake, police said."

"He explained to the astonished officers that he had really wanted to grow sunflowers," police said in a statement on Tuesday. "But because he didn't have any sunflower seeds, he instead scattered half a sack of old bird seed he had at home."

The hemp seeds contained in the bird food flourished. "The friendly elderly gentleman was surprised at the strange plants that had grown next to the flowers but didn't realize they were cannabis plants,"

He promptly ploughed up the field with the tractor under the watchful eyes of the police."

Stuff happens.
