People always lie

Rain rain. Brain drain. Drain my brain to refrain from insane. The brains main drain occurred due to cocaine piled in the formation of wain. Pulling your mane, pulling the chain that's tied 'round my vein to help keep me sane. Got lots to gain if I retain the pain you inflict with the cane, not letting it wane. I'm neither Lois Lane or Tarzans Jane but you're not even bat-Bruce Wayne, and a membrane is "a thin, film-like structure", citizen Kane. Train in vain 'cause you're still plain and this is not the right terrain to reign over.
