Mr Logic is a fictional character in the British comedy magazine Viz who is portrayed as being humourless, friendless and emotionless. He takes everything said to him totally literally and is entirely unaware of what is intended when a metaphorical statement is made. He also is unable to understand puns, for example he reads a joke from a Christmas cracker which says 'what is the difference between a buffalo and a bison? (you can't wash your hands in a buffalo)', to which he replies 'you can't wash your hands in a bison either'. His only purpose in life is to correct people in their grammar, knowledge or intention when they speak, often resulting in a violent reaction.
Here is an example; Mr Logic is in charge of the till at the local off-licence
In a similar episode, Mr Logic visits a post office and asks if they sell postage stamps. When the woman working there answers, "Of course, how many would you like?", Mr Logic corrects her by informing her that he only wants to know if they sell stamps, and that a purchase does not have to follow. He then proceeds with telling her that he does "at present require a First Class stamp."
In another episode Mr Logic was onboard a flight where the Captain announced that "If you look out of the window to your left, the Swiss Alps are below us." Mr Logic responded by pressing the attendant call button and informing the stewardess that "The physical presence (or indeed absence) of a mountain range does not ipso facto depend on whether or not one looks out of the window." As a result, the pilot jumps out of the plane rather than having Mr Logic point out another inaccuracy in his words.
He lives at the Fulchester Community Housing For The Differently Tempered, and has had various housemates, all of whom have had severe anger management problems. For instance, one of his housemates threatened to "break every bone in [his] body", causing Mr. Logic to point out that given the number of bones in the Human body, it would be impossible for the housemate to carry out his threat. The housemate then proceeded to prove him wrong. Another strip saw him go on a date with one of the female residents of the facility. Inevitably Mr. Logic managed to set her violent tendencies off with his behaviour, resulting in her murdering him (though it wasn't the first or last time he was killed at the end of a strip).
Mr. Logic was inspired by Chris Donald's own brother, Steve, who was much later diagnosed with Asperger's syndrome. His first name was also given as Steven in an early strip, though it later changed to Lawrence.
