Spike: (Gives Ducky a look that reads "Do it")
Ducky then grabs Petrie on the shoulders in an attempt to scare him
Petrie:
Stop!
Don't touch me there.
This is my private square.
R-A-P-E!
Get your fingers off of me!
(The real ending is "Get your p***s out of me", but I had to modify it to make it suitable for the caption)
EDIT: (Sorry for any mental scarring. If it was the first two lines, check them over. If it was Petrie's quote, it was a joke from my camp. Sadly, we are not the most clean jokers.)
