Back in the old days (i.e. 2005) Shane Nickerson had a very popular blog and at one point he arranged a very funny photoshop contest all about changing famous album covers to feature Worf (A Star Trek Character, for the non-geeks).
Although this is some very crude photoshoping, we all thought it was very funny at the time. If i remember correctly I think I even scored some kind of award for the Bowie/Worfie cover. Check out the full gallery of all the submissions, as Shane has not had the heart to close it down, as of yet – or perhaps he has just forgotten about the whole thing.
