It's always good to make your mark in a WhatsApp group with a witty opening line. 

However you'll have to go some way to top this Irish Mam's opening first ever WhatsApp message. 

David McGinn tweeted yesterday that his dad had bought his mum her first ever smartphone as a birthday present. Thus she was introduced to WhatsApp for the first time and added to the family WhatsApp group. 

She received a message welcoming her to the family and then replied with the below zinger. 

We think she's going to be a great addition to that group.
