What they did started out as a joke, then people expected them to perform music at shows.
The US national anthem, the music part is based on a very old British navy drinking song.
There is another drinking game with a Slovene connection.
Every time Slavoj Ziezek pull on his shirt collar in a speech or interview your supposed to take a drink if your a philosophy student HA HA…
Yes I know its a nervous tick but its still kind of funny.
