This is the only episode (of over 98 eps) in which the otherwise always over-correct and quite humourless 'Kommissar' Erik Ode had a laughing fit. Furthermore this ep was completely differently shot as all other eps were being filmed typically in the fashion of 'those days television'. Its like a 'film noir' but nobody has ever noticed or commented on it. Its an extremely interesting piece of filming amidst of very standardised tv productions at that time.
