Do not give Darth Vader-themed stuff to fathers-to-be.
Darth Vader killed billions of people, including his own family (Owen Lars was his stepbrother), assisted in the oppression of an entire galaxy, tortured people without any twinge of remorse, and spent years trying to kill his own children. He committed genocide on several occasions, was violently xenophobic, killed people indiscriminately, and also strangled his pregnant wife because she was upset that he had beheaded several dozen children.
Also, he beheaded several dozen children.
This is not a good role model for fathers.
