Yup. That gem is the lesser known, but Emmy-Award winner, "Taxicab Confessions" on HBO, of course.

Okay, not exactly rom-com viewing material for the first date with your girlfriend who never misses a Jennifer Aniston premiere. Rather, 'tis the sort of stuff to tuck away for darker, introspective moments when you are stuck in the house without better entertainment...also useful viewing for taking your mind off illnesses such as accute insomnia, tornado-phobia or prolonged, life-threatening food poisoning from Chinese cuisine you had in alphabet city, Manhattan - yes, me!
Misery does love company, and many of these characters reveal, in documentary form, their life of dancing on the edge... Dig in and enjoy.
