It's just boring. There are so many genuinely funny things to say about Australia but this is played out. Like if everytime someone mentioned the usa people were like "Oh are you afraid of being shot? bet you have to constantly watch out for being shot huh? shot?" or if when the UK came up it was just "Queen and empire right haha bet you eat shit food huh?" (actually people do this and it's also not funny especially when you can tease them for all the genuinely hilarious shit like the house of Lords and the London museum).
