Seconding this; perhaps the taunt could have two "styles"? One that lasts a few seconds, and one that cycles like the Rancho and the Pool Party. Valve has neglected the Heavy for far too long when it comes to taunts, and I think the Heavy sitting on a chair and commenting on the book would make a GREAT cycling taunt. Perhaps you could make him say the "oh my god" from the Meet the Heavy, the chuckles from the positive voicelines and the "da" from the "da, this will work".

Just a thought. He could also sit on his Minigun.

One thing that Valve actually showed in Poker Night at the Inventory is that Heavy himself stated that he has a PhD in Russian literature and when asked whether he uses it in his line of work, he states, "More than you would think." This would be perfect for the Heavy, as Valve seems to have forgotten this little fact.
