We round up the best clips from Instagram this week.
Just grandmas being grandmas.
You know when you start typing a friends name in a post on Facebook and it automatically identifies their page and tags them? Well Grandmas keep signing off messages to their Grandkids with 'Grandma' and accidently tagging themselves as hip-hop artist Grandmaster Flash.
Some are completely unaware that they are doing it.
Some grandkids have chosen to ignore what their grandma has done.
Some Grandmas are totally bewildered at the situation.
And others are just being normal, adorable grandmas.
