"Because its not right" the Doctor replied, after a brief moment of hissing through gritted teeth and hoping on one leg from the pain that surged through his foot. His hands began to stroke the top of the ancient coffin, his finger tips tracing the hieroglyphic writing. "King Tut's sarcophagus weighed one point three six metric tons. This one weighs far more, and it's not for the right reasons. It gives the appearance of being made entirely from gold and stone, but it's not. It's made from something else."<br/><br/>The Doctor stepped back before holding his hand over the lid of the sarcophagus.,his stare was grim as he gazed down at it. "Do you feel that?" He asked. "That pressure? That odd force that seems to push everything away. Almost as if it's telling you not to touch. Dangerous things lurk within."<br/><br/>The Doctor traced his finger up the side of the coffin, his eyebrows raising a little as he ran his fingers over a bump in the gold. "Oh... now that is interesting," he said before feeling around the odd protrusion.<br/><br/>"Tosh you're about to do this museum a great service," the Doctor said, struggling a little as his fingers picked at a switch in its side. "You're about to help reveal this sarcophagus as a fraud and save everyone's time," he said before something clicked on the side of the tomb. A suddenn odd beeping sound began to emanate from the golden coffin. It's surface began to flicker, revealing an odd shape below it that was oval and dark.<br/><br/>"Because this isn't a sarcophagus," he said before stepping back as the golden face fell away completely, revealing a very large crystal that was buried in the face of the oval object. "It's a prison cell from space."
