A senior class has pranked their head teacher by sneaking into her house and having a surprise sleepover in her kitchen.
The students at the boarding school in Delaware concocted the prank after being invited to the teacher's house following senior prom.
Joy McGrath, the Head of School at St. Andrew's in Middletown, came down for a coffee in the morning to find 70 senior students camped out in her kitchen.
A video of the prank has gone viral since the school shared a clip on its Instagram page.
Text accompanying the video said: "It's senior prank season and boy did the Class of 2023 get Ms. McGrath good. Last night, the ENTIRE senior class snuck into her house at 1 AM and bedded down for a good night's sleep all over the first floor of her residence.
"No, she didn't wake up!"
“I was in shock. They were in every possible corner like sardines,” McGrath told Today. “It took me a second to realise, ‘This is a senior prank!’”
The boys got into Ms McGrath's house after McGrath’s husband, Ty Jones, intentionally left their front door unlocked.
In the video of the big reveal, the head teacher opens the door to her kitchen and finds the students sprawled across the room.
A little shocked, she retreats back behind the door before reappearing and saying, “Good morning, little bunnies!”, which is met with laughter.
The pranksters conjured up the idea after they were invited round for breakfast.
“Someone joked that they wouldn’t mind going to bed right there in the living room,” the 18-year-old KaiChun “Austin” Chuang told Today, “Then a couple of us glanced at each other like, ‘hmmmm.’”
The students agreed “to go straight to bed” in order to not wake up Ms McGrath.
“I can sleep through anything,” Ms McGrath said.
In a letter to the school published on May 26, Ms McGrath said she wasn’t bothered by the prank.
“How can I be upset when this place really is a dream?” she wrote. “It’s just funny that in our cell phone-limited and social-media-shunning school that anything we do — much less the most ordinary of moments — could ‘go viral.’ ”
