Always loved the "advertisement" from Shackelton:
MEN WANTED: FOR HAZARDOUS JOURNEY. SMALL WAGES, BITTER COLD, LONG MONTHS OF COMPLETE DARKNESS, CONSTANT DANGER, SAFE RETURN DOUBTFUL. HONOUR AND RECOGNITION IN CASE OF SUCCESS.
Sounds like a marriage proposal...... (except the honour and recognition part.....

Disclaimer..."No trace of the supposed advertisement has come to light."
Have "Endurance" on the Kindle, just need to find the time.
