You shoot your anal lasers through their connecting smelly bits.

You laser rape each of them (ass-to-ass).

You climb onto the roof of the car and dump a huge laser cake, which burns through on top of the teens.

You shoot your anal lasers at the gas tank until it explodes. (yes, I realize this may not work in reality)

You shoot your anal lasers through their heads while they're kissing.

You shoot an anal laser under the car, darting through the bottom and into their chests.

You knock on the car door. One teen says "Who is it?" You say "Anal" He says "Anal who?" You say "Anal lasers, bitches!" And then you shoot them to shreds.

You shoot out a solid laser, which you call an "analsaber" and you proceed to chop-up the teens while making lame Star Wars references, such as "You don't know the power of the Anal Side!"

Or “When I left you, I was but the anal laser learner, now I am the Anal Laser Master.”

Or “The anus is strong with this one.”
