@thebattlecalculatot: You can rip out of his webbing....many characters have done it before. And again, Spider-Man doesn't possess the strength to physically down the Thing. Him being a 10 tonner, despite having feats above that put him in a 15-20 ton range, is still vastly weaker than Namor, Thor, Iron Man, the Hulk, and so on with all the other class 100+ characters the Thing has tanked hits from.
@esquirehulk: If you know the rules then why do you continue to rage then and get yourself likely banned if you keep it up? It's not like it is going to enforce your point anymore, whether it's wrong or right.
