Četiri tikvice, molim vas means “Four courgettes, please”.
If you are not quite sure what courgettes look like, just picture something that has had a bit of sugar sprinkled on it – one clear image is enough. To pay, you take out your purse with the jazz record and the huge animals on it, the image for four from the body list: četiri. Then one courgette is a touch too big and everybody makes jokes about it – touch (Tick in German) and jokes give you tikvice.
From here on the limousine stands for molim vas on its own, so the stories do not get longer than they need to be.
