Get the sleep on it mug.
when someone says something really stupid or obvious that ruins a good joke, everyone but the person who killed the joke goes to sleep. this makes the person who made the killing comment realize that they are an idiot and that they should leave the country.

You have been awake for 18 hours and are now viewing this useless definition of sleep. You are very tired and your brain is not functioning at its normal capacity. The bags under your eyes are starting to weigh you down. It's 1:30am and you have to get up at 6:30am for work. Another coffee wont help you now...
Turn off your computer and get some sleep you net junky!!
