Is that a joke, or does circumcision or its absence actually have an effect on the classifier? Or do you refer to some other characteristic? Offhand I can't really think of a more marked difference between American and non-American penises than the relatively high US circumcision rate, but I'm not so much a subject matter expert as just an interested amateur, and perhaps I overlook something here.
(If anything, I'd expect the classifier to more reliably call "not hot dog" on a penis that's circumcised, since hot dogs rarely are.)

I'm pretty sure he means the app is only available in the US store and not commenting on the shape or size of american "hot-dogs".

Hey, the show did a whole scene about taking a dick joke too seriously, I figured a comment doing the same could work. I appear to have been wrong about that! Or, at the very least, I need to work on my delivery.
