LMAO. Taguchi's always the "weirdo", but i think he's just "special".
the other members will be talking about one thing and he'll always change the subject or say something really random. and he always has his puns and sayings: "Iriguchi, Deguchi, Taguchi desu~!" is his most famous one.
it means "Enter (or Entrance), Exit, I'm Taguchi" LOL.
