As a new meme was launched at this year's Zend/PHP Conference & Expo and, while it's not directly related to PHP, it was still very warmly accepted by the community - Christian Flickinger's "Fails" logos (see here). He's written up a post about it for his blog too:

So, a week before PHP|TEK 2008 I came up with the genius idea to take the Ruby on Rails logo, which is protected against re-use (hahaha), and parody it. I wanted to express my views of Ruby on Rails (though never have using RoR) through this modification.

I took the logo and simply changed the "R" to an "F" using a font that was almost identical to the original.

You can ask anyone that was at ZendCon this year about them - they were everywhere. Christian did a great job on a simple parody that shares the sentiment of many members of the PHP community (and others outside I'm sure). He has them for sale on his etsy shop if you'd like to pick up some of your own.
