Writer's Almanac with Garrison Keillor:
"The longest entry in the 1989 edition is the word "set" in its verb form: There are more than 430 listed ways the verb "set" is used. The entry for the verb "set" is 60,000 words long, the equivalent of a modestly sized novel. The Bible is quoted more than any other work in the Oxford English Dictionary, and Shakespeare is quoted more than any other single author. Of Shakespeare's works, Hamlet is quoted the most — there about 1,600 quotations from Hamlet alone in the OED."
