Will and Henry talk to Dad about the end of the school year slump, singing The Wellerman as soloists in the choir concert, the pool finally getting filled with water, the bass that Dad put together with Will, Phoebe's birthday, Moon Knight, and Will's teachers complimenting his tastes in music.  In the News, we talk about the world record for the youngest mariachi singer ever, a the drone display that rickrolled Dallas on April Fool's Day, and a fossil found that is believed to have belonged to a dinosaur that died on the day of the asteroid strike.  We discuss some hypothetical situations.  Finally, for Treat Yourself, we try some limited edition flavors of Van Leeuwen French Ice Cream, including elderflower and lemon royal wedding cake, pizza and Kraft macaroni and cheese flavors.
