LOL! For Pitt, debating with a bunch of fanboys about whether Wolverine's claws could scratch Captain America's shield would be "better" than broaching the subject of Hoaxmas.
Well, in the Ultimate universe, maybe. After all, Wolvie's claws and the shield are both made out of adamantium there. But in Univserse 616? Nah. There's it's been shown that only Thor and Thanos have been able to destroy the shield, and Wolvie's not in their weight class. (Nor does his name start with "th", which is another important requirement.)
My brain remembers this stuff, yet I can't remember my own phone number...
