The pear thing is from a popular internet meme seem a lot on certain image boards.

The pear goes with the phrase "Lol wut" whenever someone posts something completely non-sequitur to the thread topic. There's a few different "lol wut" pictures, always something completely weird, but the pear is the only one that's stuck around.

There's also "pic unrelated" for when people post something but the image they post with the text has nothing to do with it. There are some pretty bizarre "pic unrelated" images too.
