Frans Vrolijk

Goede tijden, slechte tijden, also known as GTST, is the longest-running Dutch soap opera, revolving around the lives of the families Alberts, Sanders, De Jong, Van Houten and Bouwhuis. It all takes place in the fictional town of Meerdijk.

Professor Archibald Chagrijn exposes the world to his blubbering gas, which makes people sad and causes them to cry. Bassie proves immune to the blubbering gas -- as he has had an overdose of laughing gas. The professor is hiding on the Canary Islands, but Bassie and Adriaan manage to track him down.
