Phone bill

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's the problem? We all use our work telephones!"
