Participation is easy: Just make a LOLcat out of it (or, hell, do something else randomly creative with it; it's for fun, after all). You can do this at a number of places:
- ROFLbot or Lolcat Generator let you save the result to your computer, and you can then re-upload it to an image hosting service like imgur and paste the image link here
- Cheezburger's Lolbuilder appears to do the work of hosting it for you, but you have to enter an e-mail address to get the link sent to you
Go wild!
