Please try to stay on the topic of off-topicness, please.

Is it possible to go off-topic on an off-topic thread? I guess that would be to stay on topic. But then every other post would be another topic! But changing the topic every other post would be staying on the topic of being off-topic..!

Ahhhh the conundrum!
