Many images in this compendium are very uncommon throughout the Internet hence the name. Many of these uncommon images have tongue-in-cheek pee-pants humour, thereby they were banned from the Internet for several decades until fans wanted to revive them. Wikipedians reserved images for encyclopedic uses only, however, oddball images from the UnCommons were allowed for Uncyclopedic websites.
A strict policy involves uploading the appropriate images. The image has to be good enough for viewers to accept. Generic images that humor an audience can be added to the compendium to accomodate Uncyclomediacs.
