They both are pretty good with voices actually.... and hearing Tom do a funny voice is hilarious because he seems so serious all the time....he actually can do Homer Simpson pretty well...and when I saw him in Chicago there is a scene where he is supposed to throw his voice and be talking as if he was Roxie Hart who sits on his knee like a dummy...and to me that never sounds like him either.... Unless I am mistaken, the tall skinny brother was John....and the shorter, wider brother was Tom.
