There is a food substitute intended to supply all daily nutritional needs, known as ""Soylent"".

Don’t be impatient Arnold and Isaac were residents in a nursing home. Even though they were best of friends, they were still prone to argue with each other. One day, they are queuing up at the canteen to get their lunch. Because Arnold is taking his time, Isaac says to him, "Hey you! Hurry up already before I punch you in the teeth." Arnold turns round, looks at Isaac and says, "OK. Go ahead. Make my day! My teeth are upstairs in the glass by my bed."
