Small, insignificant weeds that some superstitious people beleive are made by small green fairies, who dance and sing in an Irish accent and love gold in pots under rainbows. Therefore, these unitellegent people find this weed lucky, and they go on long idiotic hunts to find one. Most people are utterly disapointed when they come up emptyhanded, because most people can;t find four leafed clovers.
Gee look: Four leaf clovers! Just like in the lucky charms cereal! Wow!
