Penny is putting some vapor rub, very unhappily, onto Sheldon’s chest and Sheldon insists she sing this hilarious Soft Kitty song. They Lyrics are:
Soft kitty, warm kitty
Little ball of fur
Happy kitty, sleepy kitty
Purr, purr, purr
This amazing bit of The Big Bang Theory humor has now been made available for you to wear (soft kitty t-shirt) or hug (soft kitty plush doll). The Big Bang Theory tv show never fails to amuse me.
