Some kind of Voyage up my own Arsehole

Leap! raw red piles like a bouncy castle threshold
There the sweetcorn of self-doubt
A trapped bolus of indecision (like a Haywain)
The black scabs of burst hubris,
Five undigested meals cooked by dead girlfriends.
a Hungry Hungry Hippos ball
sprouts of despair
fat fat fat &c.
Lampreys and tapeworms tying themselves in slimy sexy knots.
Dante and Beatrice, both voiced by David Jason.
Duct tape all up one side
An appendix with its own appendix (?)
Pancreatic lipase dunked
in a bit of yellow feather.
Moonraker panel,
a different obscure reference.
Bit that looks like lichen,
like compost, like Quaid,
lego man's hand,
caving in bit,
dense black bits,
A key.
