That Run Was Perfect!!!

• UUHHH, You caught that, RIGHT????

12
See Doc,

• I told you it wasnt going to work that way!!

13
Whaddya mean you deleted

• all my video source files because you thought
  they took up too much room??

14
Plot 210 Data Points??

• Hey,
• you want them, you plot them!

15
Ramon and Dales bogus adventure!!
