Thankyou so much for reviving the earworm to end all earworms, Tom Lehrer's multiple-pastiche Clementine. There goes my afternoon.

"Era leggera
E come un fairy
E s'wear shoes numero nine
Herring bo-o-o-oxes
Senza to-o-o-opses
Sendale per Clementina
Si! per Clementina
Si! per Clementina
Sendale per Clementina
Sendale per Clementin'"

It goes on. Oh, how it goes on.
