An officially licensed The Big Bang Theory mug featuring a cute depiction of a kitty with a thermometer in her mouth along with the words "Sing Soft Kitty to Me!".
Soft Kitty is Sheldon's song of choice when he's feeling unwell as his mother used to sing it to him as a child. Although Penny was reluctant to sing the song to Sheldon when he first asked, she later grew to like the song as she asked Sheldon to sing it to him when she was on medication for a shoulder injury.
