n.b. this poem should only be read upside down in blue pencil

i’m an autistic on
the poetic spectrum
i want a microphone
but have accepted i can’t sing
there are two types
of words, it seems to me
words that rhyme with
and words that mean the same as
i’m a rabble douser
a sub-intellectual
active on the couch,
always ineffectual
in vest and briefs
and sandals and socks
trying the door knobs
testing the locks
thinking of
five minutes mary,
so called because she always
wants five minutes mair
i’m up her street
rinse and repeat
bring down the government
no bobbies on the beat

i heard a nonsense poem on radio 4 once maybe 20 years ago that i’m sure had a line that someone’s name must be spelled upside down in blue pencil but i have searched high and low (ok, i asked claude) and i haven’t been able to identify the original inspirational work. maybe it was dadaist? maybe the pencil wasn’t blue? perhaps it was a crayon? if anyone has any ideas, i would welcome them.
