  • 'If-so, fact-o.'

  • As in "Half a bee, philosophically, must, ipso facto, half not be." From Eric the Half A Bee by the Monty Python team:

    Half a bee, philosophically, must, ipso facto, half not be.
    But half the bee
    has got to be,
    vis a vis
    its entity - do you see?

    But can a bee
    be said to be
    or not to be
    an entire bee
    when half the bee
    is not a bee
    due to some ancient injury?

    Singing...

    La dee dee, 1 2 3,
    Eric the half a bee.
    A B C D E F G,
    Eric the half a bee.

    Is this retched demi-bee,
    half asleep upon my knee,
    some freak from a menagerie?
    No! It's Eric the half a bee.

    Fiddle dee dum,
    Fiddle dee dee,
    Eric the half bee.

    Ho ho ho,
    Tee hee hee,
    Eric the half a bee.

    I love this hive employee-ee-ee (with buzzing in background)
    bisected accidentally
    one summer afternoon by me
    I love him carnally.

    He loves him carnally... (together)
    ...semi-carnally

    (spoken)

    The end
