"Home Alone" star Macaulay Culkin Sunday tweaked Internet hoaxsters and social-media sites that had proclaimed him dead by humorously demonstrating he was still alive.

"Performing last night at the Belmont, Bernie style ? #imalive," read a tweet on his band The Pizza Underground's Twitter page, accompanying a photo of Culkin, 34, slumped in a band mate's arms at the Austin, Texas, gig. The post alluded to the dark comedy "Weekend at Bernie's" (1989), in which two young corporate drones (Andrew McCarthy, Jonathan Silverman) have to manipulate the corpse of their boss Bernie Lomax (Terry Kiser) to pretend the man is still alive.

On Saturday, the comedy rock band -- which does pizza-themed takes on songs by The Velvet Underground -- had tweeted a photo of a smiling Culkin holding a soft drink, captioned, "We're on tour you silly people." Immediately following this was a shot of Culkin and others on a street corner, captioned "One of the great things you can do when you're alive is stop for lunch in Breaux Bridge, LA." The Pizza Underground, for which Culkin plays percussion and kazoo and contributes vocal, had played the Freret Street PubliQ House in New Orleans on Friday.

As the urban-myth debunking site Snopes.com documented, a Facebook memorial page, since removed, had that, "At about 11 a.m. ET on Thursday (November 06, 2014), our beloved actor Macaulay Culkin passed away. ? He will be missed but not forgotten. Please show your sympathy and condolences by commenting on and liking this page."

Hundreds of thousands of social-network users believed the page, Snopes said, despite no evidence on journalistic news sites that the claim was true.
