"This is NOT Mel Torme"

HELLO, BOYS! I'M BACK!

"...one ping only."

"Yippee ki yay..."

"Beware the beast Man, for he is the Devil's pawn. Alone among God's primates, he kills for sport or lust or greed. Yea, he will murder his brother to possess his brother's land.

"When this guy sneezes, he looks like a party favor."

 

"But from where?"

"Do you know the Klingon proverb that tells us revenge is a dish best served cold? It is very cold in space."
