The goat head thing

On level 30 of doom 2, when you teleport into the big room with the goat face picture it says something. It sounds like it's something backwards. Any idea what it's saying?

It says, "To win the game, you must pay me, George Romero, $500."

OH YEAH! Now i remember. Though i dont remember the "pay me $500" party. O well.

Actually, it's "...pay me $500 for the second part of Doom 2."

To win the game you must kill me, John Romero.

Read the FAQ, thanks.
