Weird but interesting traditions

For those who have read the tradition essay, here's an interesting example to showcase those points...
This tradition is somewhat similar to the tomatoes-throwing festival in Spain.

- tradition provides opportunity for family and friends to come together to celebrate
- the tradition contributes to the cultural identity of the group, causing them to be unique and different from other groups
- this uniqueness can be a selling point for tourism, as tourists want to see something different from their homeland
- serves as reminder of the past, as this festival is to commemorate a rebellion against tyranny in history (provided those celebrating the festival actually know about this history and are not just mimicking the form without any cognizance of the meaning behind it)

- while the rationale is noble, the way of celebrating appears controversial....seems like a wastage of food...other controversial traditional practices include bull fighting in Spain (the bull is killed at the end of each performance, cock-fighting in Thailand, and an interesting one in Spain where they jump over babies to rid them of bad luck, see HERE)
