April Fools' Day pranks can be in good fun, but not when your favorite celebrity's life is on the line.

Gossipmongers don't wait until April 1st to start causing trouble; no, they churn out frighteningly believable death rumors about stars every few months. Wayne Knight of Jurassic Park and Seinfeld fame is the most recent actor to falsely fall victim, allegedly dying in a tractor trailer crash.

Instead of letting reps deliver the good news, the man better known as Newman jumped onto Twitter to prove he was very much alive.

Knight isn't the first celeb to strike back online at this type of morbid hoax. See how many other famous faces – who are still kicking today – reacted to their drummed-up online death rattle.
