I have, over time, captioned quite a few LoLs over at the I Can Haz Cheezburger? site. Generally this is for my own amusement. Occasionally, some of them get seen by others and get chosen to go on the viewer's list of favorite
One of my Lols recently got posted to the front page of ICHC's celebrity captions site, ROFLrazzi. The front page is where you want to be, because that's where you get lots of votes and even, hey!, comments. The groupies and the cash come later, I guess.
Here's the LOL, in all its glory:
This has actually gotten over a thousand votes so far. More proof that puns may be the lowest form of humor, but they're also the second-most popular, right after seeing some guy get hit in the crotch.
Here's a link to my LOLz page on ICHC, where you can view my other low puns, smartass remarks, and twisted interpretations and captionings of various photos. Some of them are actually funny, once you get past the sullen, bitter misanthropy. (I should probably put a link to that page in the sidebar.)
