This week's question is about some odd English phrases. One of them is Bob's your Uncle which people say to mean it's simple or straightforward. Bob is a man's name but why his name is used is a mystery.
We also explain other idioms that use people's names. Listen out for Steven, Tom, Dick and Harry.
Another expression that gets used is to catch a flick. You can catch a bus or a fish but in this context the word means something else.
The word flick is slang for film or movie. So what do you think catch a flick might mean? Listen to the programme to find out.
