I am looking for a specific scene from a children’s show, it was a British one and there’s a character who is trying to get to sleep but he cannot sleep so he calls his mother to get him a drink of water.  The character is either a child as in a character played by a child actor or portrayed as a child, or an adult trying to imitate a kid.  He exclaims ‘Mommy, can I have a drink of water?’.  It may have been animated.
