Using the bizarreness effect in marketing is about leveraging things that are bizarre, especially those that are incongruous and out of context, to stand out and be more memorable.
As explained by Seth Godin of Purple Cow:
“If you travel on an airline and they get you there safely, you don’t tell anyone. That’s what’s supposed to happen. What makes it remarkable is the service is so unexpected (they were an hour early! they comped my ticket because I was cute! they served flaming crêpes suzette in first class!) that you need to share it.”
