And spiderman is having Jack O'Neill for dinner tonight.

Ans I thought it was Blancmange Telescope. Sod it.

...was that all about. Can someone please explain?

I think it's what happens when you leave buttons with enticing words like "Start a new game" lying around, and allow random people to wander onto your website. Let's hope Jack O'Neill doesn't work in any kind of nuclear facility.
