Co Sister Puns

But I couldn’t connect the Dots

Her sister was studying for her math test when she asks, "what is cos? (co-sign)" When her dad pipes up, "It's when two people sign a document." Sister, "....."

Context: My mother's maiden name is Shearing and she had been at her parents, helping them out for a few days (they live far away) and had been talking about getting the wifi password, which was difficult.

So she said that she phoned her sister, but that a co-worker of her sister picked up. After being asked if he could help, my mother replied "Well unless you can tell me my dad's wifi password..." He laughingly replied "Sorry, that's not the type of information we share in this office."

Now my dad looks across the table, smiles and says "It's not the type of information they Shearing that office?"
