I have three theory.
1, I'm completely misunderstanding his posts, because they're written in some old/funny English stylea nd non of the other two theories make sense
2, He is an intelligent guy, who is just fucking with you, and sometimes he even falls out from his role. Like he did in the obama tv q&a thread - didn't write in his usual style.
3, He never falls out from the role, he is sometimes on drugs and sometimes not.
If "fall out from a role" doesnt mean anything in english, than sorry.
:D I mean "he cant focus on the role, and writes normally"
