When you reach for you tea cup in the middle of an movie....DON'T do it when you know there are a scene building up that will make you lift an inch or two from the couch!!!!
What will happen is that, you will get tea all over you and some on the couch too!!!
In other words...you will have to change clothes and curse a lot! (or in my case...laugh....since I knew what would happen right before I jumped)
