Who is in charge around here?

The boss was complaining in our staff meeting the other day that he wasn't getting any respect.
Later that morning he went to a local sign shop and bought a small sign that read: "I'm 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!"
