There's one episode of the Netflix original series The Ranch where one of the characters asks his father if he'd like to watch something on Netflix, and the laughter goes really wild over this line. I guess it's funny because it's a Netflix-original series and they mentioned the service, but is it really that funny?
After all, if a character on a TV show asked "wanna watch something on TV?", we probably wouldn't be going wild with laughter. If the show was produced for cable, we probably wouldn't laugh so hard if somebody said "want to watch something on cable?" We probably wouldn't be laughing if somebody in a theatrical movie said "want to go to the movies?" So maybe we'd be laughing if they asked if they wanted to watch something on a specific channel that the show was broadcast on, but this "wanna watch something on Netflix?" joke seems odd.
In a way, it seems like Netflix original series are a bit of a niche, but at the same time, it seems like Netflix is significantly growing with original series. Maybe if Netflix had fewer original series', or if it was the first Netflix original series, it'd be a much funnier line.
