At least once a year I watch The Big Lebowski and, within a week, end up drinking White Russians and taking a bath. I don't usually do either. For some reason I try and compress the two activities into one.
Taking a bath while drinking a White Russian is a bad idea. The drink just sits in your stomach curdling in the heat. Remember that the Dude never drank in the bathtub, just smoked. So don't try and drink in the bathtub. That's my advice.
