An example of life imitating art occurred on March 1st, 2022 when the car carrying cargo ship Felicity Ace sank off the coast of the Azores. Headed toward Quonset (not Quahog), Rhode Island, it was carrying nearly 4000 Volkswagen Group luxury models including Audi, Porsche, Lamborghini and Bentley.
Ricky Gervais is the voice of Billy Finn.
The title is based off the phrase "be careful what you wish for".
