Wow, those guys are fast! I can't help but feel impressed by their abilities, even though part of me sees the foolishness of their bravados.
As for messengers being working class or not (ha, you thought I wasn't paying attention, huh?) : messengers are some of the poorest people I know. And staying poor in spite of working their asses off. I don't know if that fits the whatever definition of working class, but I kinda don't even care. I sympathize with messengers, and will always respect the hard, dangerous, honest and badly-paid job they do. As my grandfather would say, it's an honourable job.
