You bang and bang the adamantium skeleton of chest but adamantium refuses to bend to your will. In frustration you swing your hammer and BANG adamantium skeleton of chest really hard making it shake violently. You feel like you really FUMBLED this time. You curse everyone to hell loudly. You curse everyone to hell. Adamantium skeleton of chest shakes more and more violently every second until the structural integrity gives in with loud groan and the whole thing just collapses down. What a mess!.
