Zombie Elvis Found!
"Zombie Elvis Found!" is an in-game joke, and possibly an easter egg in Grand Theft Auto III and GTA Vice City.
Basically, "Zombie Elvis Found!" is a headline on newspapers that are found on the streets throughout Liberty City and Vice City. The newspaper depicts the headline, along with a black and white photograph of Elvis' face.
This is an in-game joke towards the hysteria that revolved around the alleged "sightings" of Elvis during the 70's and 80's after his death.
