I'd like to think that g-train's mindset goes on its own, forgive the pun,
"train of thought", as it were. Its very similar to School House Rock's,
In his head there's a smaller version of him running a train station that
is his whole thought process, so he grabs words and puts them into
sentences, only he generally gets that "I know that's an absurd thought"
part of the song A LOT more often than most people.
g-train has also been arrested several times for talking drakes and demanding
to know what they would say if they could speak. But hey, he's just keeping
it gangsta, you know how it is.
