EPISODE IDEA!!! 20 Questions: PVP Edition

The host sends each competitor an object.
Each competitor has to ask the other competitor a series of questions with the goal of guessing the object.
Like the previous episodes, the fewer questions you ask under 20 the more points you receive for guessing the item.
HERE'S THE CATCH: Without lying, each competitor has to give answers that make it as difficult as possible to guess the object provided to them by the host!

The competitors want to try to sabotage their opponent as much as possible to prevent them from guessing correctly. However, the host (i.e. the only person who knows what both objects are) acts as a referee to make sure that neither competitor tells an outright lie that makes it impossible to guess correctly.
