This didn't actually happen to me, and it isn't exactly a typo, but I think it is freakin' hillarious. This is an excerpt from an essay written about John Milton. Note that this was not intended as a joke in any way.
"After Milton got married, he wrote his epic poem
Paradise Lost. Upon the death of his wife he wrote
Paradise Regained."
