The boss was complaining in

The boss was complaining in our staff meeting the other day that he wasn稚 getting any respect.
Later that morning he went to a local sign shop and bought a small sign that read: 'I知 the Boss!' He then taped it to his office door.
Later that day when he returned from lunch, he found that someone had taped a note to the sign that said: 'Your wife called, she wants her sign back!'
