I have a virus

I seem to have a virus
I don't know what it's called
my brain has foggy thoughts
and at stupidity I'm enthralled

my mobility is restricted
I wobble more than walk
I mumble incoherently
when I try to talk

I try to show how fit I am
do press ups on the floor
expecting a bit of praise
if not a full encore

I have strange desires
to get off my chest
like a trip to Barnard castle
cos my eyes need a test

it's like I have pneumonia
and poliomyelitis
but everyone just laughs and say
you've just got Borisitis
