Around the time this website was made, I was building an application for a big company in Spain that was to run as a Java applet and required the code to be signed.
They did not yet have their own certificates so I had to make my own CA during testing and sign the code, and I wanted to make sure that they did not forget to switch to their certificates later, so instead of signing the code with my name which some bureaucrat might decide to not bother changing, the code was signed by Britney Spears.
They noticed it, got the joke and made sure to switch certificates for the release. Everything went well thanks to Britney.
