    "The eighteen-hundreds were a time for rum.\nThe nineteen-hundreds were a time for fun.\nThe two-thousands are a time to run\na civilized classroom.".repeat(Math.floor(Math.exp(Math.PI)+Math.E))

Your teacher doesn't want any numbers, but since they are an english teacher, they've got no clue what `Math.floor(Math.exp(Math.PI)+Math.E)` means.

More readably:

    "The eighteen-hundreds were a time for rum.\n\
     The nineteen-hundreds were a time for fun.\n\
     The two-thousands are a time to run\na civilized classroom.".repeat(Math.floor(Math.exp(Math.PI)+Math.E))
