A bus 7 minutes late during rush hour, that's funny.
During rush hour, bus arrival times are randomly distributed between 7 minutes late and "so late that you could say the next bus was 1 minutes early" (Any later and you just can't prove whether the bus that arrived was 30 minutes late, or the previous bus was abducted by aliens)
