A friend of mine helped me out with that. According to him, it's a Wild Wasteland encounter that hint's to a game idea or something that got ridiculed at Something Aweful. But I never really understood it myself. Look it up in the Wild Wasteland wiki on The Vault, it might tell you more.
Ahh...
Johnny Five-AcesEdit
Occurrence: During Barton Thorn's quest, you're instructed to investigate an overlook south of Goodsprings. There's a dead Prospector up here named Johnny, wearing glasses, with a glass pitcher next to him, and five aces on the table. On the cliff are four balls in a line.
This is a reference to the failed game project Zybourne Clock, more specifically to its protagonist, "Johnny Five-Aces", as well as a metaphorical explanation of time-travel involving four balls placed on the edge of a cliff. Initially announced on the Something Awful forums, the project featured questionable artwork and somewhat convoluted plot material, and eventually became a forum meme.
