- How exactly did Det. Brodka know what Bart's phone number was if he didn't ask Bart for it?
- Despite the Try N Save being shown in this episode only (and maybe a few others, but this gets the most focus), the Simpsons presumably go there to get their Christmas photo taken every year. Which means they could be regular customers at the store, and it's possible that either Brodka or someone else who works at the store asked the Simpsons for their phone number for whatever reason (notice how he mentions Bart by name without having to ask for it either — maybe this wasn't the first time Bart got in trouble with Don Brodka).
