There's not too much I can say to shed light on this page.
The jokes are there in the name Transylveinia (no, it's not just a spelling mistake!), the side-splittingly funny reference to blood-suckers and, of course, the knife in the road.
It's obviously not so cool to admit it now but - as this clearly demonstrates - back when these comics were written, Morecambe and Wise were just as big as an influence on teenage humour as Monty Python!
Who'd a-thunk it?
