This place is full of funny signs. Wait till you see the one from the bathrooms with directions about where to upchuck.
This is in the radio issue room at McMurdo. I love it because I was in Germany earlier this year and was constantly confronted with signs that seemed like they ought to be readable but never were (not for me anyway). Also, when I was a kid my parents didn’t want us to know what they were talking about, they would speak German. They had met in Germany and both speak the language well, but when they needed a word they didn’t know they would make it up and then break out laughing.
