The Fake Lottery Ticket Prank is Staged

If you've seen a video where a dude gets a lottery ticket and hollers around and calls his boss, tells him off and quits and then announces a divorce to his wife, whom he's been pinching when she's been sleeping, then tells his (best?) friend that he's been cheating on him with the best friend's wife... The sketch is so believable that it's really impossible to say at first sight whether it was real or not, so I decided to snoop around a bit.

Proof:
Original upload by user adamray24

At 0:05 seconds, the small tv set shows "Adam Ray TV", so you know.

Another original upload, this time at funnyordie.com — the site's logo can't be seen well on third-party YouTube uploads (because they are too low-res and information is not clear based on these):
"America's Funniest Home Video" (note the quotes, which mean to tell that it's really not America's Funniest Home Video tv show)

Furthermore, the uploader there is Adam Ray, too, and his avatar is that of the protagonist in the video.

Moreover, if you click on "Additional Credits" well below the video at funnyordie, the section will expand to show names of other actors from the video (who are good).

So you know.

This doesn't mean there aren't home video uploads around that show real people doing about the same stuff in real life, but the video at hand is even better than real :>
