Laces Jokes

At an Army reception center a volunteer was undergoing an IQ test.
“Well, Nicholson, determine what it is - it’s a piece of the soldier’s equipment which has two soles, 12 holes for laces and is worn on man’s feet?
“I can’t guess, sir, ” was the reply.
“But it’s easy, man. It’s a pair of shoes. Now tell the board what piece of the soldier’s equipment has the same but twice more: four soles, 24 holes for laces and is on man’s feet?! ”
“Dunno, sir. ”
“Come on, man. It’s two pairs of shoes. Now the last question-what has six feet, wings and flies in May? ”
“Oh, that easy, ” cried the volunteer, “It’s three pair of shoes! ”
