You are queueing at the airport with three colleagues, everyone with two suitcases – so you need a really big taxi: I need a taxi for four people each with two bags.
In the story the taxi driver is a huge egg that never eats dates (I need), an apple is lying on the passenger seat and is standard in this taxi (a taxi), he cuts it into four slices (for four), one of you has to pee into a plastic bucket (people), in the boot a hedgehog dances the cha-cha (each) and whispers hoarsely (with), lays a cloth over the suitcases (two), and embroidered on that cloth is a bear playing a guitar whose neck is bent like a snake (bags).
