Igor tries to arrange for a chandelier to fall upon the heads of the unsuspecting visitors. This mirrors the episode of "Only Fools and Horses" called "A Touch of Glass", in which the Trotters accidentally destroy a chandelier in a similar fashion, one of the plot points for which that sitcom is famous. The inclusion was probably made because David Jason not only played Delboy Trotter in "Only Fools and Horses" but also provides the voice for the character of Count Duckula.
The only episode in the series with Igor's name in the title.
Scott and Laura hail from Tuscaloosa, which is in Alabama. However, they don't have the accent of their state of origin, likely because they may have studied in the north.
