Labatt's is one of two beers* I've ever drank where I get the headache part of the hangover as I'm drinking the first beer. It tastes like skunk. And I've drank all manner of shitty beers, from Jacob Best to Old Frothingslosh (the beer with the foam on the bottom, which honestly tastes like a dishrag).
* the other beer was actually a malt liquor, viz. Lazer (pew pew pew).
