It's my alarm clock's fault. It's never been the same since I hit it with that sledgehammer

I was attacked by a squad of army ants

I'm not actually late, I'm early for tomorrow

I was trying to get the static charge out of my clothing

We have a really old toaster that just takes ages to warm up in the mornings

An elephant was hogging the water fountain
