Walter Cronkite, a twentieth-century icon, passed away recently.  He was famouse for the way he brought a newscast to a close. 

"And that's the way it is..." he would say.  It's horrible to say but shouldn't his epitaph read: "And that's the way it was..."

Descartes was a French philosopher in the 14th century.  Although he made many valuable contributions to the sciences, like solving geometric problems with algabraic equations, he's probably best remembered for this quote: "I think, therefore I am."  Shouldn't his epitaph read: "I thought, therefore I was."
