Written and performed by Michael Mears.
Always on the look-out for the slightest sign of infection, Arnold constantly feels unwell and his bathroom houses a filing cabinet crammed with medication.
But he has a glimmer of hope, which is to be proved a descendant of Charles Darwin.
The family connection would cheer him up considerably, because the great biologist was also what we know Arnold to be - a hypochondriac.
