He Might Have Wanted It For The Afterlife

In a 2005 article for my Egyptology class:

The team may have also located Tut's lost penis, which was catalogued during the 1920s but absent during the 1968 x-ray examination.

Though researchers could not be certain, they said the penis is likely loose in the sand next to the body, surrounded by skeletal fragments such as vertebrae, thumbs, and other missing digits.

Phew. And we thought it was gone forever.
