premise: Several males gather around a shirtless, white panted with ankle bells and a pearl necklace as he blows something from his mouth to create a ball of fire. hypothesis: Several men watch as a street performer plays the guitar.
contradiction: the first sentence talks about a person who blows something from his mouth to make a ball of fire, and the second talks about a performer who plays the guitar.  The first sentence is also missing the object (a shirtless, white-panted WHAT?  man, woman?).
