Given this was posted on Trollstation's youtube page, and they're fond of their "pranks", we were a bit dubious at first - but it is heartening to see commuters' reactions when a woman complains of unwarranted sexual advances. 

It's worth mentioning that the woman featured does have to complain quite loudly, and repeatedly, before anyone takes notice (to be honest, it's even a bit unnerving that some commuters ask if she knows him, because that would make it ok?!). Therefore - if this does happen to you on the DART home - don't let it go unnoticed.
