you knew that:
"The biggest cause of hiccups is
 eating
to fast.
Back in 1922 Charles Osborne of
 Iowa
must have done just that, because he got a case of the hiccups. Actually
 his
hiccups started while he was weighing a hog.
This was no ordinary case, it
was a
world record hiccup fit, it lasted 68
years up until they mysteriously stopped in 1990, hiccupping an
estimated 430 million times. He died 1 year
after his hiccups stopped.
In the early years Charles
Osborne
hiccupped up to 40 times a minute, which in the later years slowed to 20
 times.
Charles Osborne, however, did
manage a
somewhat ordinary life, he was married twice and had 8 children."
