Again, what is important here, is that a past action (to go to the hairdresser’s) has an effect on the present: he looks very different.

Now, watch this short video and construct a nice sentence describing the final scene:

 

Our proposition: The astronaut has eaten too many beans. He has farted and will be killed.
