"Um Goku, what is that awful noise?"
"Earth music, I didn't really listen much when I lived there, but this is just painful."
"Meh, let's go, the aliens are leaving too, this music is horrible."
Meanwhile...
"Uh... Mr. President, what's with the cigar?"
"Oh shush, the plan worked, aliens gone, answer anything people ask by saying it was a... Training accident."
Even more meanwhile.
"The addiction serum didn't work, the game busted after the Bieber storm of death, pain, and horror which drove them crazy."
"Well, it's time for plan B, I got the idea from Toy Story... death by monkeys!"
"Uh, sir? Are you sure the Bieber thing didn't affect you?"
"Baby, baby baby ohhhhh!"
