Doc mentions kidney stone options as: surgery, or laser treatment, or passing naturally. One surgical option involves making a tiny incision into where the stone is, inserting a laser, and zapping the stone into easily passable bits. But the most common treatment does not involve any cutting. An ultrasound precisely locates the stone, then a tuned and focused burst of sound shatters the stone. This does not work on the obese since fat layers absorb the soundwaves.
This episode marks the final appearance of Janice Bone, played by Robyn Addison. She appeared in nine episodes in total.
In one foreboding scene, that seemed farfetched in 2017, the group of bridesmaids were all wearing face masks, which would be commonplace worldwide 2-3 years later.
During the party, the early 1980's disco/R&B song "Don't Let Go" Written by Chris Rae and Frank McDonald (originally used in the movie Creepshow) is playing.
Janice mentions to Morwenna that Al winds up dating all Doc's receptionists, which is a kind of fan-service since fans know that Al's dated Elaine (for one episode), Pauline (for several seasons) and Morwenna.
