Bewarw of the Scots

King Edward is marching into Scotland at the head of the English army. Just over the border he sees a small kilted figure on top of a hill. As they get nearer the figure jumps up and down and screams insults at Edward.
Edward turns to a big burly English sergeant.
“Take a couple of men and sort that Scot out”
The sergeant gallops forward with his men, and the little kilted figure runs away behind the hill.There is the sound of clattering and banging and then silence. Suddenly the little kilted figure is back on the hilltop screaming insults louder than ever. Edward turns to his lieutenant
“Take a company of men and really sort that irritating Scot out”
The lieutenant gallops forward with his men, and the little kilted figure runs away behind the hill.
The banging and crashing goes on for ages and ages - then silence. Then the little kilted figure is back on the hilltop once again screaming insults louder than ever. Edward turns to a knight.
“Sir Kight, Take a whole battalion and kill that impertinent Scot”
The knight gallops forward with all his men, and the little kilted figure runs away behind the hill.
The banging and crashing goes on for ages and ages - then, as before, silence.
Finally a lone figure covered in sweat and blood staggers back towards Edward.

“Sire” he groans, “It is a trap. There are two of them”
