A phone call I just had with my mother:

Mum: "Just ringing to make sure that you are both home and don't need a lift from anywhere."
Me, with tears in my voice: "Mum! We both had exams this morning! Why didn't you wake us up?"
Mum: "What!?!"
Me: uncontrollable laughter
Mum (who never swears): "You little shit!"
