I bet it really went down like this:
Dave: James, dude! I got some great lyrics for this song im working on.
*Dave hands paper to James*
James: (while reading) ...WTF?!
Dave: Pretty good isnt it?
James: This is pure garbage, get the fuck out of my site.
Edit: I suddenly have the urge to watch Some Kind Of Monster again just to see Mustaine cry like a baby on there.
