Read the comic here.
The two Morpheuses (Morphei?) are getting along quite well, no?
When I was younger, one of the most evil taunts I could come up with to annoy my brother was the "say what you're saying while you're saying it" game. The Morphei aren't doing it on purpose - quite the opposite in fact. But the end result is pretty much the same.
Also of note is the sound effect "FIGHT!". RC has a long tradition of overly literal sound effect captions.
