After you get the Blue Haired Lawyer, Squeaky Voiced Teen, Kearney, the Tire Fire, and the Lemon Tree... Burns Mystery Boxes pay out in one of 2 set patterns (or possibly more, I'm still working on that). If you keep track of what you get you'll know exactly what comes up next.
Here's a section of Pattern 1: (X = skip)

• K M S O 3 X V L
  
• K X S O 1 B V X
  
• K M S O 3 X V L
  
• K X S O 1 B V X
  
• K M S O 3 X V L
  
• K M X O 1 B V X
  
• K M S O 3 B X L
  
• K M X O 1 B V X
  
• K M S O 3 B X L
  
• K M X O 1 B V L
  
• X M S O 3 B V X
  
• K M S X 1 B V L
  
• X M S O 3 B V X
  
• K M S X 1 B V L
  
• X M S O 1 B V X
  

Pattern 2 is a bit more complicated but pays out at the same rate.
