This is subject to change at any point, these are the first that came to mind.

Not in any particular order, but I can watch any of these at any time, and they NEVER fail to put a smile on my face. Perfect entertainment, all of 'em.

• House on Haunted Hill (Either version)
• The Frighteners
• Office Space
• Any of the Pink Panther flicks (especially Shot in the Dark)
• Pit and the Pendulum
• Casablanca
• Batman: The Movie (1966)
• Sweeney Todd: The Demon Barber of Fleet Street
• Wall-E
• The Dark Knight

Hard to limit myself to 10, really. Could easily fill another list.
