Answer:
There are three kids. Bean, Harold, and Lizzy. They are on top of a building. From a friend they heard that if they say an animal and jump off the building they'll turn into it, and land safely on the ground.
Bean and Harold wonder why they brought Lizzy. She's just plain mean.
Bean goes first. LION! He turns into a lion and lands safely.
Harold goes next. FROG! He turns into a frog and lands safely.
Lizzy's last. Um, DONKEY! Lizzy splattered on the pavement. She was already a jerk.
HA HA HA HA HA! So funny right? No wrong answer. It's a terrible joke.
