From Muppet Wiki

George and Barbara Brush are cleaning tools of the White House establishment. Caricatures of George and Barbara Bush, the Brushes are made from a hairbrush (George) and toilet brush (Barbara), accessorized minimally but appropriately. Though not strictly Muppets, this patrician pair was featured in Cheryl Henson's 1994 book The Muppets Make Puppets. George and Barbara also accompanied her in appearances on various talk shows, such as Marilu.
