This is easier than a wine tasting because what ever would you do with 4 open bottles of wine? Quite simply, go to World Market and buy their specialty beers (you can buy a 6 pack of various flavors). Have a beer tasting - serving small portions in little shot glasses - and use plain popcorn as a palate cleanser.
This goes over a little better if it accompanied by something like fantasy football research. I mean,it's beer, but most guys are not wowed by the tiny cups part. I, however, was thrilled to death at my creativity.
