Our reading
An editorial interpretation.
That's a comic mix of protest and proof. The speaker announces being in shock, a dramatic claim, then offers evidence in the form of a blanket, as if holding one settles the matter. The humour is in the irritation and the self-satisfied, slightly ridiculous logic.
