Some interesting facts I found on Google about four-leaf
clovers:
"Approximately 1 in every 10,000 clovers has the four-leaflet
form." - Wikipedia
"Legend also holds that if a lady hangs a four-leaf clover on
her door, the next man to come in will become her husband." -
Wikipedia
"The current record holder is a Pennsylvania prison inmate,
George Kaminski. While serving time on a kidnapping conviction for
the past 25 years, Kaminski has gathered 72,927 four-leaf clovers.
He found them, one at a time, hidden in the grass of prison
yards.
Kaminski was not available for an interview, but a caseworker at
the minimum-security facility in Mercer, Pa., relayed a few
questions and answers by phone. Kaminski said he started finding
the clovers to show a younger inmate who was depressed that 'you
can do anything you set your mind to.'" - The Washington Post, March 17, 2005
