Ok, so it sounds like it would be something digusting or obscene, but it's not.

I'm currently in the middle of troubleshooting some MSI / MSP installation issues on a Citrix server and I've come across a very common MSI info message that always makes me chuckle.  Here it is:

MSI (s) (04:30) [11:09:24:439]: Found shell folder  by spelunking through the registry.

According to Wikipedia, spelunking is the recreational activity of exploring caves.  While exploring caves has nothing to do with traversing registry hives/keys, it does remind me that even those developers at Microsoft (that everyone loves to hate) have a sense of humor.
