A tiny, sleeping dormouse snores like a trucker as he's weighed by the U.K.-based Surrey Wildlife Trust during a survey of nesting boxes. Even though he gets thoroughly manhandled, the adorable critter never wakes up.

Despite his comically loud snores, this little fellow isn't suffering from sleep apnea. Rather, he's hibernating for the winter. A dormouse, in fact, can spend up to one-third of its life hibernating, and will do so whenever food becomes scarce. (Yep, this video has come up before. But this time he's back on the Web -- and with sound!)
