It's not hard to see that this was put together by a Brit. Knowing that, it's also not hard to get the "Pack of cards" reference, as well as the questions about rugby, cricket, and soccer being called "football".
You'll notice I wasn't the first one to get 6 balls to an over in cricket... and who doesn't know there are 8 tentacles on an octopus? Where do you think it gets it's name "OCTOpus". Octo, Octa and Oct as a prefix always means 8.
