Jerry Seinfeld's onscreen adversary and Michael J. Fox's TV baby brother were both targets of trending death hoaxes over the weekend.
Both Wayne Knight, best known for playing Newman on the 1990s show "Seinfeld," and former child star Brian Bonsall, who played Andy Keaton on the 1980s sitcom "Family Ties" are alive and well, OTRC.com has confirmed.
Knight, 58, took to Twitter to debunk the rumors of his alleged demise, which appeared to have originated from a parody TMZ website.
"Some of you will be glad to hear this, others strangely disappointed, but...I am alive and well!" the actor tweeted on Sunday. "Does someone have to DIE to trend? Geez! Thanks for all the love everybody. I didn't know you cared. Glad to be breathing!"
"Regrets to my friends and family who were shocked this morning and the family of the woman who actually died in my 'supposed' accident," he added.
Bonsall (pictured below) also responded to his own death hoax on Twitter. His appeared to have originated on a phony Us Weekly article.
"Well apparently i'm dead, lol but I'll have you know I'm doing well and enjoying a cup of coffee at home," he tweeted.
Bonsall, also known for his role as Worf's son Alexander on "Star Trek: The Next Generation," quit acting at age 13 and is now a musician, living in Colorado
Wayne Knight: "I'm having a glorious St. Patrick's Day"
Knight played Newman on "Seinfeld" between 1992 and 1998 and recently reprised his role in an episode of Seinfeld's web series, "Comedians In Cars Getting Coffee." He is also known for his role as Dennis Nedry in the 1993 film "Jurassic Park."
One fan posted on Twitter a photo of a dinosaur that attacked in "Jurassic Park," saying: "Initial reports are that this is the suspect who started the @iWayneKnight is dead hoax..."
Knight gained scores of new followers on Twitter due to the death hoax.
"Thanks to the small town of new followers who came onboard just to tell me they're glad I didn't kick! I feel good about the result as well," he tweeted.
