I'm not sure "crash course" is exactly how we want to describe this thing.

Next, Hub visitors may take a glided tour - The Boston Globe:

He envisions packs of about eight -- each led by a tour guide who would first put participants through a 30-minute crash course in driving the [Segway] machines -- departing from Downtown Crossing and making their way through notable sections of the city.

And on the same page as this story in the Globe (when I read it) appeared a Victoria's Secret ad touting "up to 60% off bikinis." Woohoo. That sure doesn't leave much on.
