One afternoon, Joe is high on a ladder putting up lettering outside āJohnson and Pollocks Engineering.ā Heās got as far as āJohnson andā so he shouts down to Bob, āHey Bob, pass up the letter P will you?ā Bob looks around the back of the van, searching high and low, then shouts back, āI canāt find a P. The only spare letter I can find is a B!ā āOh shit,ā shouts down Joe. āWerenāt we supposed to use the B this morning at the London Brick Manufacturers?!ā
