The Boss

from jokesgallery.com amongst others

A manager was complaining in a staff meeting that he wasn't getting any respect.

Later that morning he went out and got 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!"
