- And You Thought It Would Fail: The comics creator Jan Kruis actually thought this when he first started the series back in the 1970s. When it became an unexpected success, he even feared he would run out of story ideas to use.
- Hilarious in Hindsight: In one comic, Catootje and Harold (a boy from her school) decide to switch houses for a while. When Jans hears about this she sarcastically remarks "great, I always wanted a son". A few years later, Gertje was introduced into the series.
