One thing I enjoy drinking once in a while is an Irish coffee. Have you ever had one?

I love Irish coffee.  You need Irish whiskey, sugar and thick cream.

Also, coffee! : ) 
1_Wizard
Yea, coffee too. You are not supposed to use whipped cream but modern recipes do so.

I don't use whipped cream when I have it. I don't want the extra calories, and I just want to get down to business with the whiskey and coffee! Ha!

Originally, it was served to a group of very cold American passengers from a boat.  The restaurent owner soothed them by poring whiskey into their coffee.  So he did not use cream either

Oh, that's interesting. It's a soothing thing to drink when you're really cold. I think some people use brown sugar in it. 
1_Wizard
Yes, some recipes specify brown sugar.

To me the main thing is that the coffee needs to be really hot. Sometimes I pour hot water in the mug first, to get the mug really hot. Bailey's Irish Cream is a pretty good variation instead of regular whiskey.
