There are 160 calories in one serving of a Chuck Norris Shot.
We know this because there are 122 calories in 1oz of 151 Proof Rum (specifically Bacardi), 38 calories in 0.5oz of Grenadine syrup, and effectively 0 calories in a few drops of hot sauce. Math is how we get to a calorie number of 160.
But Math alone won't save you when the Theater gets hot and you need to radio in your coordinates to an Uber driver for extraction.
