Fezzik, the giant was employed by Vizzini. He doesn't have a problem with subverting the law but doesn't like to fight dirty. He is friends with Inigo; the two like to play rhyming games with one another from time to time at the ire of their employer. Fezzik is very tall and big so at a very young age, his parents made him fight competitively. He is from Turkey but met Vizzini in Greenland where was unemployed. He hates working for Vizzini, but he would rather work than go back to the circus where he originally came from.
INIGO: Vizzini...he can..fuss.
FEZZIK: Fuss, fuss...He sure likes to scream...at us.
INIGO: He probably means no...harm.
FEZZIK: He's very very short on Uh...charm.
INIGO: You have a great gift for rhyme.
FEZZIK: Yes yes...some of the time.
VIZZINI: Enough of that!
INIGO: Fezzik...are there rocks ahead?
FEZZIK: If there are...we'll be dead.
VIZZINI: No more rhymes now, I mean it!
FEZZIK: Anybody want a peanut?
FEZZIK: I can't swim, I only dog paddle.
