When it comes to making a website, I don't have a clue as to what I'm doing. In fact, I'm not even using my own computer here! However, a website could be dedicated to funny stuff happening to GB.
The cartoon shows could be adapted with change in sound. Not only this, but people could submit their own funny stuff including home videos of what they would do as real Ghostbusters.

If someone made this site, I would make GB the clay animation style! GB would blast the ghost and it would morph into a blob of clay!

Chad would probably do something like that if enough people submitted enough material.

Then again, I'm not Chad, so that has a good chance of being wrong.

I could easily throw together some flash movies if anyone wants them done, just give me some material or ideas and I'll whip em up.
