A mom, her child and a policeman are waiting at the bus station, and the bus is late.

Child: "Mommy, when's that bus coming?"

Mom: "Shhhh baby, it's on it way".

After 5 minutes, the bus is still not coming and the child is getting anxious:

Child: "Mommy, where's that bus already?"

Mom: "Oh, baby, I think it's just around the corner. It'll be here in no time."

Couple of minutes more pass:

Child: "Mommy where is the bus now?"

Mom: "It had a flat tire, my child. It'll be here as soon as they change a spare one."

15 minutes later:

Child: "Mummy, where is the bus already?"

Mom: "Oh, it got dirty after all the repairs, they just went to the car wash, they'll be right here soon enou..."

Cop: "Why the hell did they need to wash it now, I'm late as it is!"
