Sometimes we like thigs that are not really legal. Let's watch again the 2nd video. That was the one you liked more but... did you know it is not legal at all. Now you are going to be a detective. Watch it again, observe the pictures. Can you notice anything?

This 3rd video has got two typos? Do you know the difference between a typo and an error? an error or mistake is when you didn't know how to do or write something, whereas a typo, you know how to do it or how to write it, but when you type, it is done in a wrong way. So, can you identify the two typos in the title of the video?
