If ever an episode highlighted the sheer differences in characters, this is it. Harold hopes for a night of classical music, whereas Albert hopes for a musical evening with slightly lighter notes. Naturally it all goes wrong, and Albert begins cobbling. The scene that follows the pair clash is absolutely side splitting, all Hell breaks loose as the pair release all manner of pent up frustrations with one another, Albert with his hammer is so funny to watch. You watch it, and believe the pair had a load of fun making this one.
They go from hating one another, to needing to work together, back to hating one another again, it is very, very funny, and as is so often the case, it's the old man who has the last laugh.
Albert so lacking in cultural sensitivities, such a good contrast to his son, his mimicking of Harold's pose was very funny.
