I don't really look at myself as the kind of person who craves attention, but I've never been to therapy so there's probably a lot of stuff about myself that I don't know.
It's hard to really articulate what the parameters are that make one song parody-able and another song not, but if I can come up with a good enough idea for it, I go for it, and if not, then I have to move on.
In fact, when I come up with an idea for a parody I try to resist the urge to Google the idea to see if someone has done it already because the answer is almost always, "Yes, of course they have, they've thought of it!"
I've always known that if I recorded an album, it would come out, and people would enjoy it! Whereas if I wrote a movie script, chances are better than even that I'd just be another guy in L.A. with a movie script in his drawer.
