"Hello,welcome to today in Disney history, a show where I tell the viewers what happened this day in Disney history,now,today is June 28, 2012.So,we'll take a look in The Disney Book and see what happened in past on June 28. Now on page 179, section three, this book tells us that the Mickey Mouse cartoon, "The Plow Boy" is released. This film was actually the debut of Horace Horsecollar, my favorite very unused Disney character. So, you see, Horace is never more than a supporting character, sadly, but he continued on the be a character in The House of Mouse and That 1990's featurette. Okay,next, in the year 1940, the first Pluto series cartoon is released. It was named Bone Trouble, and is very funny, you should watch it.]]
