  • Gentle Jane was as good as gold,

    She always did as she was told;

    She never spoke when her mouth was full,

    Or caught bluebottles their legs to pull,

    Or spilt plum jam on her nice new frock,

    Or put white mice in the eight-day clock,

    Or vivisected her last new doll,

    Or fostered a passion for alcohol.

    And when she grew up she was given in marriage

    To a first-class earl who keeps his carriage!

    -- W.S. Gilbert, Patience

  • I participated in the vivisection of a frog last year. We bathed it in cocaine first, so it died happy. I subsequently removed its heart, which continued beating for an hour afterwards.
