Good One

The phone bill was exceptionally high and the man of the house called a family meeting. On a Saturday morning after breakfast.
Dad (Family head) : 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.

Mom: Same here, I hardly use this home telephone as I use my work telephone.

Son: Me too, I never use the home phone. I always use my company mobile.

Now everyone is looking at the Maid.

Maid: So what is the problem? You all use Your work telephones and same with me.
