Wakabayashi, a trouble-making kid sitting just behind Kasuga, played with him, sneakily cutting his hair from behind without telling him.

Kasuga was chosen as a member of the Kanto's all-star American Football Team as a defensive end.

He spent his university years by taking part-time jobs such as a sales clerk position at Seibu Dome.

One day, six years since their debut, a TV play writer called Wakabayashi in person and told him "Kasuga has no talent as a tsukkomi.

Wakabayashi, then the boke of the duo, relayed the comment to the then tsukkomi Kasuga, but he initially thought Wakabashi was just joking around and did not believe him at all.

Kasuga walks heavily and slowly with his proud 101 cm chest expanding toward the center of the stage.

[citation needed] Kasuga has represented Japan at the Finswimming Master World Cup, organized by the Confédération Mondiale des Activités Subaquatiques.

Mikio Date, a member of owarai duo Sandwichman has also said Kasuga had neither spoken ill of others nor agreed with other comedians' bad comments on others at their joint live rehearsals.

[11] His father has been very supportive of his career, making original DVDs of Kasuga to distribute to the family's neighbors, and frequently giving him advice by e-mail.

[12] Though initially against his comedy career, his mother is also supportive, distributing to neighbors the Playboy magazine when one of the issues carried an article on Kasuga.

Kasuga had a fanatical female fan called "Ochimusha" (stray samurai) when he was a football player in high school.

When he dated her, his friends called him "Moai" due to his big head, and named the two "the mysterious couple."
