When I watched the Simpsons episode where Milhouse's father makes an album entitled "Can I Borrow a Feelin'?", I never suspected that it was a reference to an actual album. Then I found this page.
What is there to say?
These are indeed the very worst album covers I've ever seen. There are some really bad ones in there - the pedophile comes to mind - but I think we've laughed most at Ken. Check out the others - you're bound to find some you like.
