If you want to see something hilarious, get a 12 join query and add "AND 1=0" on the end of the WHERE clause.
Oracle doesn't look at the query and immediately return no rows, instead the optimizer continues to generate a full plan. Apparently, according to Oracle support, they have no intention of finding "AND false" predicates to shortcut query plan compilation.
