After more than 30 years on air, Have I Got News For You is a well-established comedy series that has built a reputation for irreverent humour and satire.  Regular viewers expect the panellists to make jokes and understand that contributions are intended to be funny and amusing, and this edition was no exception.  It was clear that comedian Fin Taylor was talking about an utterly absurd scenario, in which he compared Jeremy Corbyn to Bob Dylan, and was in no way whatsoever to be taken seriously.
