Schoolbag Puns

Little me was about 12 years old when one morning my dad rushed into my room and woke me up. He told me that i was late for shool and that i need to get up and dress myself.

I, still kind of sleeping, ran into the bathroom, brushed my teeth, got dressed, took my schoolbag and right when I opened the door my dad said: "What are you doing? It's Saturday."
