Charlie Horse

Charles "Charlie" Horse likes that the pizza parlor is named after him. He sometimes suffers from a mild case of "bigshotitis" but he is a great big brother to Lamb Chop and Hush Puppy. Charlie loves bugs, worms, snakes, horror stories and anything else that will gross out Shari and his two younger siblings. Charlie loves to play his drums.

Once considered being an anchorman when he grew up, under the name of "Charles Stallion".

Tends to have ideas that eventually leads to him, and sometimes even Lamb Chop and Hush Puppy, into trouble, resulting in him getting grounded.

Charlie Horse also tends to be a troublemaker and hates the idea of having to be nice to Hush Puppy and Lamb Chop whenever Shari tells him to, and he usually has to despite not wanting to.

Charlie is best known for singing "The Song That Doesn't End" at the end of Lamb Chop's Play-Along, when Shari Lewis tries to stop them (the children, Lamb Chop, Hush Puppy, and Charlie Horse) from singing they leave, making Shari feel finally relaxed that the song was over. However the next second the barn (used when the song was playing) opens up with Charlie Horse who has come back to get the song going again but he is eventually stopped by Shari, who grabs him by the nose while telling him to stop, and this time succeeds, tells him to "go away", but before she tries to tell him another thing, Charlie Horse slams the door. Shari was actually trying to tell him not to slam the door.

The character's name is a pun on the medical condition of the charley horse, which is known to be a general, but very intense, leg pain, which is typically deep within the knee joint, in the ACL area, making walking and movement quite unbearable.

Charlie Horse appeared in "The Shari Lewis Show", and in "Lamb Chop's Play Along", and later starred in his own spin-off show, Charlie Horse's Music Pizza, about a singing pizzeria.
