On the website, Cameo, you can pay anything from $10 upwards to get a personal video from your favourite celebrity.
Ronnie Coleman is $250: https://www.cameo.com/ronniecoleman8
Kai Greene isn't available right now, otherwise I'd have him make me a video acknowledging that I'm his poet laureate.
I think the most expensive ever was Floyd Mayweather at $1,000. Mike Tyson is quite pricey too at $500. Snoop Dogg is $750.
These videos are the coolest birthday/xmas presents ever..... especially if you tell your friend that the famous person is married to your cousin's wife's brother and that's how you got them to make the video.
I might try find an openly gay celebrity and ask him to make a video for Obs. Then I'll burn it to DVD and mail it to his house.
