Album covers with hidden jokes, messages, visual gags, etc

Post album covers with hidden jokes, messages, visual gags, optical illusions, puns or whatever that isn't maybe instantly obvious

I'll start

All those Baja Marimba Band LPs that have one guy peeing in the background.  There are a handful that don't, but they released a lot of albums and most do.

We did the cover so it was a pastiche of something you would find in a Woolworth's bargain bin. We took the photograph at the most famous suicide spot in England, called Beachy Head. So, the picture is not what it seems, it is not so nicey nicey at all, and neither is the music once you take it home and buy it. We had this idea in mind that someone quite innocently would come along to a record store and see [the record] and think they would be getting 20 really good jazz/funk greats, and then they would put it on at home and they would just get decimated.
