"O RLY" in Google. So, welcome, I guess. I hope you found what you were looking for.
While I'm on the topic of stupid internet stuff that makes no sense but is funny anyway, I just have to comment on this site: YTMND.com. The basic idea is that you create a web page that consists of big zooming text in the forground, and a picture or video tiled in the background, with a sound file that plays over it. Then you post it on ytmnd.com for the world to see. This formula has led to hundreds of nonsensical but hilarious ... things.
Apparently the first one was this Sean Connery ytmnd, hence why the site is called YTMND.com.
However, the most popular one, and the one that led me to the site, was this: Captain Jean-Luc Picard. Why is this funny?! I don't even know, but it is.
This Batman ytmnd also made me laugh, as did Tom Cruise Kills Oprah.
Oh, and to relate this back to that God damn O RLY owl: Year of the Owl and rly.ytmnd.com.
Edit: This one is hilarious, but only if you play World of Warcraft.
