This may not be a great idea, but something that works at times. She can write a short funny story aboyt a person who experienced a series of troubles in achieving or doing something (this could also be a piece of a film). Te students read/watch/listen to the material and then in groups they have to guess what the cause of the problem in each case was. For example, for a person who can't pay for something, 'she must have left her wallet/purse at home', 'somebody must have pinched that!', 'She can't have had any money at all!', etc. She'd better encourage the students to make up funny and imaginary reasons.
I'm eager to see some practical comments from some teachers.
