Somehow managed to run across a website called A Flock of Segers that blends musical bands/artists names to create interesting or amusing names. Some have album cover art that is reworked to reflect the new name. I thought some of these were pretty funny, so its worth a look. My favorites were Coolio Iglesias, Minnie Pearl Jam and Englebert Humberdinck 182.
There are also some blended movie titles.
Make sure you look back through the archives by month, otherwise you’ll miss some of the best stuff.
