It's always nice to have visitors come over and stay for a while...until they start camping out at your house, eating all your food, bugging you to drive them everywhere and practically start moving in. It's times like these that you start to yearn for the good 'ol days when visitors came to you in the middle of the night, they gave you a quick anal probe and then hopped back on their ship in a beam of light never to be seen or heard from again.
