A knight and his footmen were holding a castle during a war.
One of the footmen guarding the gatehousse begins calling.
“SIRE, WE SEE A BATTALION IN THE DISTANCE”
The knight orders the men to defensive positions and rushes up the wall where the footman points at the indistinct and distant mass of men.
“What do you think? Friends or foe?” the knight asks.
“I think they’re friends sire” answers the footman.
“See any banners to think that?” the knight asks
“No but they wouldnt be huddling together if they hated each other”.
