We had a leaky drain and I called a plumber. It all went well, thanks for asking.
But while we were waiting, Coco was in continuous (and increasingly angry) disbelief about the whole thing.
See, in Ben 10 (the TV show), the group that fights aliens calls itself "Plumbers" and Coco kept trying to tell me that they are only on TV and not in real life.
Once I explained to him that it was a joke of sorts on groups like Shriners and Masons, he conceded the point. (Okay, maybe not.)
