I think the comment you're replying to was just a reflectivity fail on my part

Story time: my girlfriend asked me "why is British humour funnier?" and I wondered for two seconds and forgot about it. Then I saw shminux's comment and it reminded me so I just asked, and the assumption that British humour IS better was smuggled into my brain because it was embedded in the question I was asked. I probably meant something more like "why do I tend to like British humour better", and now it seems like a stupid thing to ask here. So I'm probably going to lean towards hypothesis 4 unless I learn something new about their culture or television networks.

Heh. I'm not really sure if all of that was worth sharing but I felt like I'd caught myself being silly so I felt an impulse to publicly admit it.
