   Hi,   
      
   Yeah, ZF only is fun. This is also fun:   
      
   ZF ⊊ ZF + (some weak forms of choice, e.g. CC or DC)   
       ⊊ ZF + Ultrafilter Lemma / BPIT   
       = ZF + Tychonoff for compact Hausdorff spaces   
       ⊊ ZF + Tychonoff for all compact spaces   
       = ZF + AC (i.e. ZFC)   
      
   Each “⊊” here means every theorem provable in   
   lhs is provable in rhs , but not conversely.
