What do you know about Hugh Hefner, the founder and publisher of Playboy magazine? Or rather, what you don't know about the Playboy kingpin? Adding to the list of rumors about him, news of his death spread across social media on Monday, which was later downplayed by the magazine mogul via his Twitter account.

Amused by the rumors circulating he commented, I'm lying in bed next to Shera Bechard with a big smile on my face, reading tweets about my unexpected demise. I'm happy to see how many people are pleased that I'm not dead.

But let's avoid those rumors and center on the truth, which says there is a lot more to Hefner that we really know. Here are some interesting facts about the legendary patriarch of the Playboy Empire.

The subspecies was first described in a publication in the Journal of Mammalogy in 1984 by James D. Lazell Jr, after his research was funded in part by a contribution from the Playboy Corporation. The Lower Keys Marsh rabbit was then named in honor of Hugh M. Hefner in recognition of the financial support received by his corporation.
