My favorite way to Rickroll someone.
First, I invite the meat over to my house for a little gaming.. maybe some Mario Party, maybe the Balder's Gate game on the PS2.. hell, Monopoly or Roborally.. whatever. We sit around and play said games for a bit, and eventually I, on the way to get myself a drink, offer to grab the meat one as well, as I'm already up. When they say yes, I get the meat whatever.. but I add in a secret ingredient..
Once the meat's passed out, I drag them into the bathroom and strip them down. I do the same to myself, and put on a raincoat. I fire up a chainsaw and dismember the body completely and use pliers to remove the teeth, then pack up the remains in garbage bags, and put all of that in to a larger garbage bag, along with the meat's clothing minus their identification. I wash down the bathroom completely and take a shower myself. I throw the meat in to the back of their car, and drive for seven and a half hours in a random direction. Along the way, I purchase a little gasoline in a portable container. Once I've arrived in a suitable location in the middle of nowhere (often across state lines) I rip off the car's VIN and license plate, then set fire to the whole thing.
Once I return home, I grind the teeth into dust and bury that a couple of hours in a different random direction, and burn the identification. The license plate and VIN I attack with an anvil and hammer, and use the metal to build a computer case. I put the various components needed to have an operation computer inside my new case, and cruise down the road where the meat used to live, using the new computer to blast "Never Gonna Give You Up" by Rick Astley.

Honestly, if you're talking BBQ and 'a guy in a parking lot' isn't part of the conversation, something's wrong.
