Things may be intense between Spencer (Troian Bellisario) and Toby (Keegan Allen) on Pretty Little Liars right now, but in real life, the actors are chock-full of silliness. Check out Keegan’s recent Keek that show the two PLLers goofing off on set...

The video gives both Keegan and Troian a chance to show off their “baby voices,” meaning the voice you make when you talk to a baby. Troian goes first, giving a soothing, even-toned delivery. Then, Keegan gives his less traditional take, which sounds more like “Muppet baby” than “baby voice.” The vid ends with Troian shooting Keegan an awesome look of mock disgust. We love them!

On a related note, does this mean Keegan and Troian will have to break out their “baby voices” on PLL? Because we’re all on-board with the teen show television trope that has high school students having to take care of a fake baby doll for health class. You just know Spencer will take the entire thing way too seriously if it’s the difference between an “A” and a “B.” For the record, we’d also be equally excited about Spoby having to babysit a real baby. PLL could do with a little lightheartedness right about now.

Which baby voice do you think is better? Are you on board with a health class baby doll plot? Sound off in the comments below!
