I remember my parents watching this when I was a child and leaving cause it looked so boring. I had no idea Masterpiece Theater indulged in such crude humor.
I just watched the whole series earlier this year, and it's actually really good. Excellent writing (adapting, I suppose one could call it), great acting from pretty much all of the recurring cast, and particularly the titular star, great production values, everything.
Five stars, as this scene came after 5 seasons of Poirot and Jap (yes, that got some getting used to) having an excellent (but strictly) professional relationship and starting to become more chummy as they each approached retirement, so it didn't just spring out of nowhere in episode three.
My mom watched every single imported british detective show that ever existed and I have fond memories of this. I did a poirot impression in my youth that was a hit at the grup parties.
Suchet has become the definitive Poirot, no other actor has come close, but then no other actor has starred in a complete adaption of the Poirot series. But still...you know.
