The Artifact
 

A group of archeologists were in Egypt excavating a tomb they recently unearthed.

Inside the tomb they found a most perplexing object wrapped in paper.

Upon further study they determined it was the petrified penis of the Perilous Prince of the predynastic period.

They sent the artifact off to the Smithsonian with their findings and waited for confirmation.

Six months later they recieved a letter from the Smithsonian stating they had not found the petrified penis of the Perilous Prince of the predynastic period but the crystalized crap of a curious chap who crept into the crypt, crapped and crept out again.

Oh, good. I thought it was gonna be another "tampon" joke. :D
