OOP: Yes, sir. (reading)
     Humpty Dumpty sat on the wall,
     Humpty Dumpty had a great fall;
     All the King’s horses and all the King’s men,
     Cannot put Humpty Dumpty together again.
Oh, look, sir. Here’s a picture of Humpty Dumpty. Why, sir, he looks like — he looks like — (turns a large picture of Humpty Dumpty towards Think-Tank and the audience)
Explanation:
 
Following Think-Tank's order, Oop read a poem about Humpty Dumpty, who had a great fall to which none of the King's horses or army people could put it again. Indeed, the poem references an 'egg' that cannot be mended back to its position if kept on a wall and has fallen down. It's just a funny nursery rhyme meant for children. And so, the picture of Humpty Dumpty is an egg-shaped cartoon. While reading that poem, the crew members got shocked when they saw the picture of Humpty Dumpty.  
 
The image of Humpty Dumpty was then displayed to the audience and Think-Tank. The crew then showed him the image, which terrified Think-Tank and caused him to scream. And Think-Tank's resemblance to Humpty Dumpty was the cause of it.
