The reason why people go to the theater is because of the element of spontaneity and the visceral experience of seeing art unfolding in front of audiences in real-time.
With the thrill of live performance is the anticipation that not everything goes as planned—whether it's a missed cue, technical glitch or a line flub.
Sort of like why people attend NASCAR races. Deep down, on some level, we all want to see the proverbial "crash and burn."
As Chef Louis, the Fuller House actor referred to Ariel's love interest Prince Eric as "Prince Albert" after singing "Les Poissons."
"I knew I should have played Prince Albert."
Immediately recognizing his ad-lib fail, Stamos corrected himself by referring to Graham Phillips' character with the proper name, "Eric."
But the damage was already done, and audiences ate it up.
But as innocuous as it was, the internet saw something more than a royal snafu.
While Prince Albert is historically known as Queen Victoria's consort and a popular tobacco, the phrase also has a NSFW meaning.
According to the Urban Dictionary, a "Prince Albert" refers to a genital piercing in which a metal ring enters through the frenulum (the part of the penis where the glans connects to the foreskin) and exits through the urethra (the duct through which urine and semen flow).
Twitter gave Stamos a royal roasting for his "Prince Albert" snafu.
It's for gems like these that we're here for live entertainment.
This isn't the actor's first foray portraying the maniacal chef. Stamos made his debut as Chef Louis during the Hollywood Bowl's 2016 performance of the same musical.
He explained to Playbill what draws him to the character.
"What's great playing this character is that he can flip at any moment; one second he loves the fish, the next he's going to murder them. He's like a Sweeney Todd character in that way."
The Little Mermaid Live is based on Walt Disney's classic 1989 animated film The Little Mermaid, incorporating composer Alan Menken's music from both the movie and the 2007 Broadway musical.
The live televised musical event featured Auli'i Cravalho in the titular role; Queen Latifah as Ursula; Shaggy as Sebastian; Graham Phillips as Prince Eric; and a very memorable turn from John Stamos as Chef Louis.
