One time when I was twelve I tried this (I knew my mom could still carry me) but she just went "wake up!" when I still pretended she left me in the car until I got up myself and admitted I wasn't asleep.
When I was little, I would do this. But I would take it to the next level. I would pull my sheets off my bed and stomp on the floor. Then I would lay in the sheets. When my parents came up, I would pretend to cry and said that I fell out of bed. They gave me attention the rest of the night.
Dat face!
