If you're lucky enough to have it, the Force is useful for a lot of things. You can retrieve your lightsaber from a distance, convince someone to let you into basically any place you want, and of course, make lunch. Even Yoda isn't above using his powers to sate his appetite a little faster, as this bizarre commercial for Nissin instant noodles proves.
Of course, Yoda being Yoda, making just a basic little noodle cup isn't enough. No, he's got to show off just how much of the Force he can channel by spinning a GIANT kettle of boiling water in the sky to make his lunch. Who else thinks Luke would rather have had Yoda cook this for him when he landed on Dagobah?
Of course, this could just be setting a bad example. A cup of noodles is so easy that a 5-year-old can make it, so why waste the Force on such a thing? Yoda doesn't need a reason, of course, but next time let's see him shill for something just a little more complicated, like Betty Crocker cake mix.
