Was Mark Twain Born on Haley's comet, and did he die on Haley's comet?

LOL, forgive me but I don't think you mean "on Halley's Comet" but when it occurred... no one could survive being born on a comet, I don't think! :p

However, there is an interesting link to more about it here

And a quote from another:
"Samuel Clemens, more commonly known as Mark Twain was born in Florida, Missouri on Nov. 30, 1835. The year he was born, Halley's Comet passed over. Twain vowed that he would not die until he saw the famous comet. Then, just before he died Halley's Comet passed over. He died the next day; April 21st, 1910, at 6:30 p.m. Mark Twain stopped breathing."

There is some debate as to whether he saw the comet or not.
