These viral photography memes have circulated the Internet like wildfire. Whether it's photographing your dog's rear end or capturing your own face squashed between a coed's thighs, these crowdsourced photo collections let anyone participate.

My favorite of these viral photography memes is Masked Avatars, which capitalizes on the swine flu craze by replacing your Facebook avatar with one in which you're wearing a surgical mask. Which is your favorite?

Implications - Viral memes can be described as Internet features that go viral and achieve a great deal of consumer attention. Companies who pay attention to viral memes will better understand what consumers find entertaining.
