I'm the boss

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 card and novelty 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!"
