First of all, let me say that I actually don't like the whole LOL cat thing. While I love cats and the occasional picture of one, I don't like the infantile misspelling and incorrect grammar that accompany such pictures. I'm sure that the plethora of such pictures of all stripes will breed a new legion of young people who are even worse than the crop which finds typing "you" to be too cumbersome a task so they type "u" or those who think that ROTFLMAO is actually a word you can say (apparently pronounced "rofflemao"). I probably have a missing component in my sense of humor that makes me immune to why the things written on the pictures are funny. I imagine it's the humor equivalent of being color blind.
That being said, I accidentally created something which my husband said reminded him of those cats and he dubbed it an LOLWombat. My friend wanted a wombat graphic for a web site he's going to make and I suggested a pirate wombat to suit the site's possible title. Unfortunately, the graphic I made is too spastic for his tastes and freaks him out a bit so he can't bear to look at it every time he logs in.
A good freak out is a terrible thing to waste so here it is for you. Personally, I see him saying things like "Yarrrr," "Arrrgh" and "Avast, ye scurvy prairie dogs!" However, you can attach any LOL-style caption you like to it as long as you don't share it with me. ;-)
