Yeh, right! Har! Freds ate Ralphs. Har! Har! Freds are lying little fuckers! Har! It'll be a warm day on Ganymede when freds eat Ralphs. Har! Har! Freds can't spell worth a damn either. Har! Ralphs already told you humans that Ralphs hate freds worse than anything in the known Universe. Har! Ralphs hate freds so much that Ralphs wouldn't stoop to eat the little maggots! Har! Har! Har!

Oh, to answer your question, human Bee-dubya-ell, Ralphs were merely sleeping. Har! The days on Ralphs' home planet are the length of your weeks. Har! Ralphs' stay awake for four of your days and then sleep for three days. Har! Ralphs are well rested and ready to get on with the annoying. Har! Har!
