Thing One and Thing Two are human-like twins from The Cat in the Hat book. They were released from the box that the cat brought in to introduce to Conrad, Sally, and the fish. The things later caused mischief by flying kites in the house which bumped the wall and also knocked everything down in their path. Conrad was able to stop the things with a net. They were also taken away by the Cat who put them back in the box. As of now they appear in the TV series The Cat in the Hat Knows Alot About That! voiced by Rob Tinkler. At some point there happens to be a Thing Three and Thing Four if the Cat ever needs extra help. In the 2003 film, Thing One is played Danielle Chuchran and Taylor Rice, and Thing Two was played by Brittany Oaks and Talia-Lynn Prairie, but Dan Castellaneta provided the voices for both of the two Things. In the deleted scenes of this film, the Things stall Joan Walden from getting home by three methods of a flood. In the 1971 cartoon short, Thing 1 was voiced by Thurl Ravenscroft, and Thing 2 was voiced by Lewis Morford. In the mid-80's, Thing 1 was voiced by Phil Hartman, and Thing 2 was voiced by Jon Lovitz.
