This one is of your mom screaming in the shower. And this one is of your grandma screaming in the shower. And one day, you'll scream in the shower.
Remember in Psycho when the lady screamed in the shower right before she (spoiler) became what's known as "super stabbed"? Well, that screaming lady, actress Janet Leigh, is somebody's mom. And that somebody is Jamie Lee Curtis.
Curtis is currently working on Scream Queens, the new horror-comedy TV show from Glee/American Horror Story creator Ryan Murphy, and yesterday she tweeted a photo from the set. (Jamie also got her start as a screamer in Halloween.) In it, she's recreating her mama's iconic pre-stab moment while holding up a photo of the original scene.
She included the date and time of the show's premiere in the tweet, because it's definitely a planned advertisement. And guess what? It's working.
