I'm trying to rationalise the amount of files floating my department's website (i'm basically going on a deleting frenzy) and in the "Events" section of the site, I've come across three random pictures of rather fat gorillas. There is another one of a gorilla "wearing" a badly drawn-on porkpie hat and glasses, and smoking a pipe.

I want to know what "Event" they were for, and why the hell I missed out on it. *sigh*
