Is where I got the moniker #1 son for the Aggie. Charlie used to call his three (?) sons by number. It’s a joke, considering I have but the one son. I watched the Charlie Chan detective movies from the 1920s in black-n-white on TV in the 1950s. Nowadays they’re considered racist (because the actor who played Charlie wasn’t Chinese) but the creators had aimed for an anti-racist theme, with a Chinese hero instead of the Yellow Peril Chinese villain common in the 20s.
