I like coffee in my coffee. If you think you need flavoring in your coffee, then you really don't like coffee.
I dunno, it can sometimes be nice to spice things up a bit. Nine times out of ten I'll have it black, but a bit of cream, Maple syrup and whiskey can really spice it up. But at the end of the day it's just coffee.
My parents got me a can of the cafe du monde stuff that's made with a bit of root chicory. Definitely different, out of the Moka pot or tends to have less caffeine, but I think this stuff is best enjoyed with milk if I had any.
But yeah, I've heard the Dennis Leary thing.
