Beavis and Butthead are basically relaxing and chilling out in a supermarket having a look at whatever they can see and Beavis find a machine which tests your blood pressure. He tells Butthead who thinks its a ride. Beavis sits down on it and before he knows it it starts crushing his arm but unlike other blood pressure devices it carries on and Butthead has to go and get help.
Again, this is not the best of all episodes however it does have a good few moments and therefore it really is worth watching. I enjoyed it myself and I have seen enough episodes to see what makes a good episode and a lame one, at least I like to think I have. This really is one that I would recommend.
