After Humphrey Bogart's death, his wife, actress Lauren Bacall, placed his ashes in an urn with a small golden whistle. Bacall had the whistle inscribed with words which she had spoken to him in To Have and Have Not
(their first film together): "If you need anything, just whistle."
[The couple named their son Stephen after Bogart's character in the film.]
[In 2003, a jeweller in Antwerp, Belgium installed a cardiograph and began selling jewelry engraved with a couple's heartbeats as they look into each other's eyes.]
