In the classroom, Smullyan is anything but leisurely or quiet.... I watched him teach a graduate level logic course, as he lurched to the blackboard (where he writes in a serviceable hand and in complete sentences) and paced about his desk, fidgeting and chuckling.
Sa silid-aralan, Smullyan ay anumang ngunit dahan-dahan o tahimik.... I Watched siya magturo ng isang nagtapos sa antas ng kurso na lohika, na siya lurched sa pisara (kung saan magsusulat siya sa isang makabuluhan at kamay sa kumpletong pangungusap) at paced tungkol sa kanyang desk, fidgeting at chuckling.
