If you ever encounter a bear in the woods, this is what you have to do.

They fall asleep...

Nice wake up call.

Cute baby battles his tiredness.

Beautiful girl can't keep her eye's open in the classroom.

Or is just a really bad driver.

This guy must have been really tired...

But is just too tired... Cute!

And refuses to wake up.

Or you might get in trouble.

Nothing comes between a child and sugar.

Taking a quiet nap is impossible in this class.

Maybe he should try snowboarding instead.

It's very simple!

After a while this would make me terrified of even falling asleep.

Cuteness overload.

The inside of his car and longs must be totally black, but he's still sleeping.

They might just give you the scare of a life time.

Cute squirrel found the nicest spot in the house to sleep.

Is he drunk or just very tired?

How did it get there in the first place?

Or maybe she just wanted a massage...

Aaaaaaaawwww!

Give him a break, he only slept for 18 hours last night.

It'll leave you with a head ache.

Sleepy driver in Russia.

Cat gives a little hug while it's asleep.
