We know little about Waldorf, except that he completes the heckling team of Statler and Waldorf (and is always seen screen left of Statler). When not saying bad things about the Muppets, Waldorf spends time with his wife, Astoria (and we presume he heckles her, too).
Waldorf is hand cast in heavy weight polystone and meticulously hand painted to the highest standards. He sits on a Corinthian-inspired plinth that evokes the image of a classical sculpture while also hearkening to the decorative motifs of the Muppet Theatre. The base also bears The Muppet Show logo and the character's name, while on the underside is listed the sculptor's name and signature, ensuring that this beautiful piece will be treasured item for many years to come.
