Two things I love about this, firstly I love Chicagoans, and secondly (sadly) I love PBR, when I was on holiday in Florida this year I brought a case to a BBQ and instantly made friends (unknowingly it was being hosted by a load of cheese-heads!). Not often can you obtain an accolade for such poor taste in refreshment!
Great video for seeing the difference between something that causes movement on the demand curve versus a move in the demand curve.
