Captain Olimar's Journal
"Detailed analysis has revealed that this artifact is extremely ancient. It's obviously an important archeological discovery, but the salesman in me is more interested in its monetary value! Maybe I'll get the best of both worlds by selling it to a museum."

Sales Pitch
"Decades of toil with nose to the grindstone. Insulting orders swallowed without a hiccup. Such is the life of a salaried man. His name will not be remembered. His family will not understand. But if the results bear out his efforts, that is enough. Now, nose to the grindstone, drone!"
