WM (Proof by contradiction):
[Assume:] Every number has ℵo successors.
 Actually, we do not have to assume that, since it can be proved (in the context of mathematics/set theory).
 An e IN: card({m e IN : m > n}) = ℵo.
 
If every number is subtracted the successors remain.
 Huh?! Just a silly (psychotic) claim. If _every_ number "is subtracted" (based on "the set of numbers+their successors"), then NO numbers (and hence no successors) "remain" [in the new/resulting set]. (After all, the successors of any number are numbers too.*)
 What did WM prove here? That he's a complete idiot?

Btw. Did I mention my cat?
