[mothered]

Myself and my brother are Identical twins and during primary school, we switched classes for around a week or so.

The teachers had no Idea, but were confused why we couldn't answer simple questions relative to the homework given to us. Of course, due to the switch, my brother's homework was mine and vice-versa.

hahhhaa, Same here.. We had a female one of them at our department and her sister in another one. They used to switch class.

No doubt, It's a common prank.

I remember like It was yesterday, yet It happened so many decades ago.
