Strange Sign on Lab Door I saw a strange sign on a door to a geophysics lab in a museum in Switzerland. I was really curious about what it means and wanted to know if anyone is familiar with this sign.



Here's the full image of the door so you can see the context/type of work going on in the lab.
I notice that the sign:


Doesn't quite match the other signs for scale or style
Isn't obvious in what it's communicating (unlike normal warning signs)
Looks like a monster (apparently "We Must All Stop ManBearPig" from South Park):&emsp;&emsp;&emsp;&emsp;&emsp;&emsp;&emsp;&emsp;.


I conclude that it's a joke by the museum staff, much like this "velociraptor-free workplace" sign at the Field Museum in Chicago.
