Some say that to build a beautiful world, we need several types of people.

On the other hand, it must be admitted that if there's one type of person that we could do without - its perverts.

Unfortunately, they are everywhere on this planet and these 20 photos will prove it to you.

Some of the pictures are hilarious, but they are still not people with whom you want to be associated with because they might leave you ashamed to be around them.

You might even recognise some of your friends in these pictures!
