Analysis of Office Mottoes

Motto heartening, inspiring,
  Framed above my pretty *desk,
Never Shelley, Keats, or Byring*
  Penned a phrase so picturesque!
But in me no inspiration
  Rides my low and prosy brow-
All I think of is vacation
When I see that lucubration:

DO IT NOW

When I see another sentence
  Framed upon a brother's wall,
Resolution and repentance
  Do not flood o'er me at all

Do I heed that ancient story:

    Proverbs void of point or wit,
'KEEP A-PLUGGIN' WHEN IT'S HILLY!'
    'LIFE'S A TIGER: CONQUER IT!'
Office mottoes make me weary
    And of all the bromide bunch
There is only one I seri-
Ously like, and that's the cheery:

GONE TO LUNCH
