One way to have more fun than watching this movie

Try asking your girlfriend what she would do if your best mate came over in a clearly psychotic and hallucinating state, and as a response to not seeing what that idiot sees, you would give everyone a 5 inch knife and turn off the lights and start stabbing at each other in the dark.

In all likelyhood it will differ from asking "What's going on" for about 20 times.
