grandads wartime arsehole

onwards and upwards
said grandad 
from his shed
he levelled his Lee Enfield 
at the enemy
who hid
up his arse
throughout the war
the entire war
the whole poxy war
every jap
hid in his crap
every hun
every nun
with a gun
didn't shun
grandads arsehole
and spent the war years
concealed in his bowels
without food or towels
and stayed there until
they died or grew ill
grandad shoved his rifle
into his arsehole
up his arse
and shot his full load
emptied the magazine
blew his tiny brains out
