1. A Danish geezer who lived in Elsinore, and suffered dreadful privations whilst deployed on operations. In addition to hoisting his stash of Danish porn, some sod left a sardine in his locker, giving rise to the phrase "something rotten in the state of Denmark". No way to treat a prince.
2. A short cigar to be smoked when all goes tits up, preferably to the accompaniment of a Bach air played by Jacques Loussier.
4. A baby ham, or a small pig.
