STAGE TUBE: Sneak Peek - 'Big Bang's Simon Helberg Guest Stars on Disney XD, 1/21

Simon Helberg, star of the CBS hit comedy series 'The Big Bang Theory, will lend his voice to this week's episode of the Disney XD cartoon KICK BUTTOWSKI - Suburban Daredevil. 

The episode, entitled 'Power Play', will air this Saturday at 11am/10c on Disney XD. Kick Buttowski is given the assignment of acting as a bodyguard for his classmate Ronaldo (Helberg). When Ronaldo wants to play on the playground apparatus known as "the Wiggler", Kick must fend off a pack of preschoolers who have no intention of sharing their equipment with the older kids. 

In addition to this dilemma, Kick has been assigned to be Ronaldo's understudy in the school's production of 'Romeo and Juliet'. Kick needs to take all precautions to protect Ronaldo in order to avoid taking over the play's leading role. 

Disney XD's Kick Buttowski is an extraordinary kid living in the world's most ordinary town in Disney XD's Emmy-nominated animated comedy series "Kick Buttowski - Suburban Daredevil," featuring action-packed stunt sequences and daring physical feats. He rebels against the mundane and strives to make every moment just a little more awesome. Determined to become the world's greatest daredevil, Kick knows that when life throws him an obstacle, his only choice is to jump it.

Small in stature but big in heart, Kick makes the most out of his suburban surroundings, by devising such stunts as riding down Dead Man's Drop on an ironing board or racing the school bus with a soda-powered jet pack. If one of his stunts goes awry, Kick responds with his customary "I'm good!" then picks himself up and tries it again. Although he is faced with obstacles along the way, Kick, like his idol Billy Stumps, never backs down from a challenge.

Always at Kick's side is his loyal friend Gunther, who enthusiastically supports his every move. Kick's other friends include Wade, a slacker convenience store clerk who is always ready to help out, and Mr. Vickle, Kick's neighbor on the cul-de-sac, who provides him with encouragement and words of wisdom.

Kick also has an older brother Brad, who relishes tormenting him, and a younger sister, Brianna, a spoiled pageant princess who covers everything with glitter - making her, from Kick's point of view, "the opposite of awesome."

"Kick Buttowski - Suburban Daredevil" stars Charlie Schlatter ("Kim Possible," Loonatics Unleashed") as Clarence "Kick" Buttowski; Matt Jones ("Breaking Bad") as Gunther; Danny Cooksey ("Tiny Toon Adventures," "Dave the Barbarian") as Brad; John DiMaggio ("Futurama") as Mr. Vickle and Eric Christian Olsen ("NCIS: Los Angeles," "Community") as Wade.
