The Simpsons family has proven to be surprisingly gifted over the years. All five members of the family unit have proven to be deceptively brilliant in their own ways, and this even extends to their artistic merits, with multiple members of the family proving some prowess in the arts at one time or another. In fact, one of them even achieved an amazing level of skill by literally just laying on their back all day.
With that said, let's look at what happened in Season 19's "Homer of Seville" and how it saw Homer Simpson become an amazing singer and painter entirely by accident.
Over the years, Homer Simpson has been shown to be surprisingly musically talented. At various points of his life, Homer has been a member of a Grammy-Award Winning barbershop-quartet known as the Be Sharps (Season 5's "Homer's Barbershop Quartet") and in a nation-famous grunge rock band called Sadasm (Season 19's "That '90s Show"). Other episodes -- such as Season 3's "Colonel Homer," Season 14's "Dude, Where's My Ranch?" and Season 26's "Covercraft" -- even featured Homer connected to the world of music, showing him to have a strong ear for song-writing and boasting a naturally impressive voice.
However, it turns out Homer can even accidentally showcase impressive musical skills without realizing it. While serving as a pallbearer at a funeral he wasn't invited to in "Homer of Seville," Homer injures his back falling into an open grave. Then, when being examined by Doctor Hibbert, Homer lets out a trademark "D'oh" upon hearing the price of the procedure, but instead of being his regular annoyed grunt, it sounds operatic. It turns out that when he's laying on his back, Homer's stomach slides underneath his diaphragm. This gives him a powerful singing voice -- with Lisa comparing him to famed tenor Andrea Bocelli, who previously recorded an entire song on his back. Homer quickly proves to be a popular and gifted singer, impressing Mister Burns enough to earn a spot in the local opera.
Becoming a star in the opera scene, Homer ends up becoming the target of an obsessed fan -- with Homer and Marge barely surviving a series of murder attempts from the scorned woman. Homer decides to give up opera, and instead focus on another hobby he can do lying on his back: panting. He quickly proves to also be phenomenal in that department, creating a replica of the Sistine Chapel on the ceiling of the family living room -- which Lisa admits is not based on any real-life phenomenon.
Artistic expression is a constant for all of the Simpsons family. In that sense, it's not surprising that Homer might have some more hidden skills, especially when considering his previous musical prowess. Even operatic singing makes a certain amount of sense, given his past musical moments. However, Homer's painting comes entirely out of left field, leaving many wondering what else TV's favorite buffoon could have hidden inside his mind
