Citrus Horn
This is really hard to explain. You see, some friends were getting married, and they were registering for gifts. One of the things they found was the above Citrus Horn, which inexplicably struck everybody as funny. And then I decided to use it in some other images, a la my Under Sedation Live spoofs.
If you think that's odd, right after I started downloading images to work with, somebody else posted some altered images with the same idea.
