I only saw him once, on a TV interview. He claimed he has memorized every single line from every single Shakespeare play, and all one has to do is name any Bard play, scene, and line number, and he can recite the line. The interviewer didn’t even challenge him (I think it was Katie Couric).
Does Mr Chopra recall this line about people like himself: “He uses his folly like a stalking horse,and under the presentation of that he shoots his wit.” (”As You Like It”) V,iv,112
