The interesting thing about this is Audioboo as confirmation of your excuse. Years ago when I was late for school, no way would teacher believe that the bus had broken down, and I'd have got 100 olines. "I msut get out of bed earlier". You can direct teacher to Audioboo and say, "listen sir/ma'am, I recorded that while the bus was broken down, and you can check the time on the recording."
You may still get 100 lines. "I must not record Audiboos in the bus queue." ;-)
