Phone bill(office humor)

The phone bill was exceptionally high and the man of the house called a family meeting.   Dad:  People this is unacceptable.  You have to limit the use of the phone.  I do not use this phone, I use the one at the office.   Mum:  Same here, I hardly use this home telephone as I use my work telephone   Maid:  So what is the problem?  We all use our work telephones.
