As the fangs of the Incredibly Deadly Viper closed on Sunny's chin, Violet and Klaus watched in horror as Sunny's little eyes closed and her face grew quiet. Then, moving as suddenly as the snake, Sunny smiled brightly, opened her mouth, and bit the Incredibly Deadly Viper right on its tiny, scaled nose. The snake let go of her chin, and Violet and Klaus could see that it had left barely a mark. The two older Baudelaire siblings looked at Uncle Monty, and Uncle Monty looked back at them and laughed. His loud laughter bounced off the glass walls of the Reptile Room.

"Uncle Monty, what can we do?" Klaus said in despair.

"Oh, I'm sorry, my dears," Uncle Monty said, wiping his eyes with his hands. "You must be very frightened. But the Incredibly Deadly Viper is one of the least dangerous and most friendly creatures in the animal kingdom. Sunny has nothing to worry about, and neither do you."

Klaus looked at his baby sister, who was still in his arms, as she playfully gave the Incredibly Deadly Viper a big hug around its thick body, and he realized Uncle Monty must be telling the truth. "But then why is it called the Incredibly Deadly Viper?"

Uncle Monty laughed again. "It's a misnomer," he said, using a word which here means "a very wrong name." "Because I discovered it, I got to name it, remember? Don't tell anyone about the Incredibly Deadly Viper, because I'm going to present it to the Herpetological Society and give them a good scare before explaining that the snake is completely harmless! Lord knows they've teased me many times, because of my name. 'Hello hello, Montgomery Montgomery,' they say. 'How are you how are you, Montgomery Montgomery?' But at this year's conference I'm going to get back at them with this prank." Uncle Monty drew himself up to his full height and began talking in a silly, scientific voice. "'Colleagues,' I'll say, 'I would like to introduce to you a new species, the Incredibly Deadly Viper, which I found in the southwest forest of—my God! It's escaped!' And then, when all my fellow herpetologists have jumped up on chairs and tables and are shrieking in fear, I'll tell them that the snake wouldn't hurt a fly! Won't that be hysterical?"

Violet and Klaus looked at each other, and then began laughing, half in relief that their sister was unharmed, and half with amusement, because they thought Uncle Monty's prank was a good one.

Klaus put Sunny down on the floor, and the Incredibly Deadly Viper followed, wriggling its tail affectionately around Sunny, the way you might put your arm around someone of whom you were fond.

"Are there any snakes in this room that are dangerous?" Violet asked.
