This is also the name of a song sung at summer camp.
Calamine, Calamine, Calamine Lotion,
Oooh, no more Calamine Lotion.
Itchy, itchy, scratchy, scratchy Oh! I got one on my backy!
Oooh, no more Calamine Lotion.
The accompanying dance to the song is a) pretend like you've got an empty bottle of lotion and then to b) hop around, scratching your back.
This song can be sung singly (with the camp counselor in the lead) or in a round.
