“Interrupting Lord Vader in his meditation chamber, Admiral Piett quickly found himself at the top of the imperial execution list.”
Who knows what Darth Vader gets up too in his meditation chamber. Whatever it is, you do not want to be the officer who interrupts his private time. Cpt. Brick imagines Darth Vader clowning around in his spare time. This Lego Star Wars MOC, titled A Bad Day for Admiral Piett, is a great example of the humor found in Lego.
