Paper Curves.
Isn't it amazing the dirty thoughts that a simple blank piece of paper can conjure up?
3.

I swear this is not actually someone's naked behind. Just look at it for a minute or so and you will see that it's actually the side view of shirtless man!
4.

Hairy Pits.
Hairy armpits look disturbingly close to a private part of female anatomy.
5.

Wild Party Guest.
I'm pretty sure that's actually the arm of the woman in front of her, unless she makes a habit of going to parties and taking off her clothes!
6.

This picture looks really dirty until you realize that both girls are sitting sideways on that stool.
7.

So that's how trees reproduce!

Sleeping Baby.
You'll feel really dirty after you find out this is simply a sleeping baby's eye.
9.

I'm pretty sure that is actually a part of that comforter. Someone please tell me that is a part of that comforter!

This poor girl has the worst (or best) timing ever! Even though it's just an arm, it's a pretty convincing rear end at a glance.

Naughty Minnie.
Mistakes happen, but Disney has to be doing this on purpose!
12.

Close Family.
This picture makes this family look like they are a little too close. No wonder they didn't want anyone knowing who they are!

Womanly Arms
That guy should be proud of his sexy arms!

Phallic Puppy.
This poor dog will forever be known as the puppy that everyone thought was a penis!

If you instantly thought that was cleavage, perhaps you don't read enough books!
