Fever

If you work and do your best, you'll get the sack like all the rest, but if you laze and bugger about, you'll live to see the job right out. The work is hard, the pay is small, so take your time and sod 'em all cos when you're dead you'll be forgot - so don't try and do the bloody lot or on your tombstone, neatly lacquered, these three words: Just Bleedin' Knackered.
