Wimzie's House Season 2 Episode 16 Identical Cousins

Because he has trouble asking for what he wants and standing up for himself, Horace has been innocently and inadvertently taken advantage of in game playing and other kid decisions. In a rare "dual" role, Horace's cousin Morris, visits for a day. Morris is nice, funny, but very outspoken and assertive. When he speaks, people listen. Horace tries to emulate Morris and goes overboard, until he finally learns how to speak up for what he wants and how he feels as himself and not someone else.
