From Wikipedia
Yuji Suzuki (鈴木 有二, Suzuki Yūji; born 5 June 1949), better known as Guts Ishimatsu (ガッツ 石松, Gatsu Ishīmatsu) is a Japanese actor, comedian, tarento and former professional boxer who competed in the Lightweight division from 1966 to 1978. He is a one-time former WBC Lightweight Champion and an OPBF Lightweight Champion.
As a boxer, he was known for his unpredictable style, sometimes marking completely unexpected victories, and often losing in extravagant fashion as well. He lost 14 of his 51 professional fights, a rather large number of losses for a world champion. Since retiring in the late 70’s, he has gained popularity as an entertainer.
He often appears as a foolish boke character on television, but this is an act he puts on for media purposes. As a boxing commentator, he offers precise, intelligent commentary based on his own experiences in the ring.
