Shortly before leaving Warner Bros., Chuck Jones created a number of toons with one-shot characters and stories, amongst these was Nelly's Folly.
This is a great story about a young singer who goes to the big city to find fame and fortune, only to become lonely and in need of a friend. In her depression, she ends up in a love triangle with a married man, which ruins her image and destroys her career.
Oh, and did I mention that this singer is a giraffe?
Yep, a singing giraffe, voiced by the late Gloria Wood (a vocalist who dubbed the singing voices for many famous actresses, and also sang the original Rice-a-Roni jingles).
