Going down………

a blond and a redhead enter an elevator being held for them by a curtious gentleman in a dark business suit. while thanking him for his kind act, they both notice that the man has flakes on his shoulders. the redhead whispers to the blond…’He looks like he could use some head and shoulders’ The blond looks at her friend and replys with a look of bewilderment…’Yes, but how do you give shoulders?’
