It's really stupid, but I have possible theory. Some people do stupid shit for to fit in, to be liked or to be seen as good laugh and one of the boys. They have a diffcult time saying no, or even come up with the idea of doing daft things themselves for a bit attention.
Most grow out of that need to impress in childhood, their teens or in earlyadulthood but it's not always the case. Some people are just insecure like that and it leads them to take silly risks.
Might be going way too far with my armchair psychology here, and to be honest I'm describing myself a bit as sad as that is so could it just be projection. It happens though.
