Little Johnny asks the teacher, “Mrs Roberts, can I be punished for something I haven’t done?”

Mrs Roberts is shocked, “Of course not, Johnny, that would be very unfair.”

Little Johnny is relieved, “Okay, Mrs Roberts, good to know. By the way, I didn't do my homework last night."

"What kind of car did you just get?"

"I already forgot, you know me, I am bad with names. But is starts with 'T'!"

"Really? Wow, what a strange car... starts with 'T'... All cars that I know start with petrol."
