Warning: watching this video may make you feel like wearing a lampshade on your head and barfing in a closet. When you watch 'Mad Men,' it seems like there's a good bit of drinking going on. You have no idea.

After watching this video compilation of every onscreen drink taken by the Sterling Cooper Draper Pryce staff ever, we wonder how the whole show isn't just people standing in the street with no pants on yelling at each other. That's a whoooole lot of Tom Collins.
