Hey, how do I download it?
This is a warmer, and there is nothing to download. It's just an idea for your lesson, not a worksheet.
Here's a short funny story for your learners. It can be used as a warm up. I usually give my students this one together with a few other short funny stories (one per student) and then give them a couple of minutes to look through their story. Then I ask them to retell their stories to the rest of the group but tell the ending in a way that it would be possible to predict the ending. They give different ideas about how the story may end, and if no one guesses right, we read the endings together.
A linguistics professor was lecturing his class one day. 'In English', he said, 'A double negative forms a positive. In some languages, though, such as Russian, a double negative is still a negative. However, there is no language wherein a double positive can form a negative.'
A loud voice from the back of the room piped up, 'Yeah, right.'
