I know. I've seen it a thousand times. I just tweeked it's meaning concerning cornfields.
One plant was growing next to one of my son's houses & no one in the house knew about it. The police were watching & waiting, to see if they were gonna havest it. Eventually, the police harvested it & the guys living in the house called it the rent plant. They figured they could have paid a months rent if they'd found it & got it sold before the police got to it.
