premise: An old man dressed as a clown leans down in front of a group of seated children and allows a girl to pet a small animal. hypothesis: The old man is 235 years old and just started being a clown.
contradiction: A man who is dressed as a clown in front of a group of seated children means that he has experience being a clown and is being called for jobs, whereas a man who just started being a clown is probably not being called for jobs.
