i am not sure what you mean about what does it say about him to you...
i think women who are clever and witty like to be with a man that can keep up and vice versa. it doesn't "do" anything for me. i just want someone who is on my level in all ways. besides, i don't think a simpleton could appreciate someone clever and witty in the same sense a very sexual person may not appreciate a prude. we are attracted to what compliments who we are.
