"I've got you now! Any last words?"
"...Olsen Twins."
"Olsen Twins? KILL!"
Props to those who know where this is from.
It's from some Final Fantasy flash, with Cactaur being a raging sociopath that hates the Olsen twins. If I remember correctly, he and Tonberry got in trouble, so they needed a way out...
Why do I still remember this?
OT: I think one of the most common is "Dude, hold my beer--I'll show you how to do it!"
For a personal experience, I had a moment where I was playing STALKER and trying to creep behind a guy to silence him, saying aloud "I'm just going to kill this poor bastard..."
And then he turned around and blasted me in the face with a shotgun. Nonetheless, I lolled.
