Judge Grindstump mentions "scaphism" as one of the methods of execution. Guybrush has no idea what it is, but Stan tells him that "you don't wanna know". Scaphism is a method of torturous execution which originated in ancient Persia. The convict was usually stripped naked, covered in milk and honey, and locked away in a very confined space that was then exposed to the sun. The milk and honey then attracted countless insects, biting and stinging the defenseless victim, and even burrowing in the flesh, causing a prolonged agony that usually ended in death from a combination of dehydration, starvation and septic shock.
Marquis De Singe gives Morgan LeFlay 30 thousand pieces of silver for bringing in Guybrush, a reference to the Biblical disciple Judas, who betrayed Jesus Christ for 30 pieces of silver.
Guybrush saying that he pleads "one thousand percent not guilty" is a spoof of O.J. Simpson claiming that he was "absolutely, 100 percent not guilty" while on trial for the murder of his ex-wife Nicole Brown Simpson and her lover.
