i hope Fan Man's son comes flying in and knocks them both out.

To be honest, IT would all depend on how he wins....
If he just plain outboxed calzaghe, then everyone would have to say, wow, peter manfredo is better than joe C. Point blank,
but if joe C is outboxing him for 8 rounds or so, and joe trips over a crushed drink cup that was thrown into the ring and lands right on manfredo's glove, then we are left with more questions than before.
