I wonder if it ' s the Hennessy itself and , if so , what about it makes it difficult to get comfortable . That may very well be the answer , but I ' m probably on a buying freeze for the foreseeable future . <| sep |> I love my Roomba too . It vacuums around or under all my furniture . <| sep |> Generating power while moving air too ? We obey the laws of thermodynamics around here . <| sep |> There is a beer called Iron City that is produced under contract by a company outside of the city , but it ' s just not the same as it was when it was produced in Pittsburgh by Pittsburgh Brewing , for better or worse . I drank a lot of iron city before and after the transition , and once it was obvious that they tasted different , I basically stopped drinking it altogether . I can ' t remember the last iron city I had at this point .
