1. How cliché is it that Justin Timberlake would use ebonics? First of all, the kid got straight A's in school and is NOT a complete moron. He may use key ebonics phrases, such as "yo" or "wassup", but I'm fairly certain he would also type out the words "this" and "that". So, just keep in mind that Justin has some brain power, and that most people don't type exactly how they talk.
2. Make sure you know where they are and what time zone they are in. They could be three hours ahead of you, behind you, whatever. Also, a good thing to know is that they are usually on stage from about 8:30 to 10:00 PM on show days. So, if you're online while they hsould be onstage, you're gonna fail in your attempt to convince people that you are them.
3. Keep the official site handy. With the new section "N Sync N Touch" you can find out what they do on non-show days and the like. Very handy when convincing people.
4. Don't use a screen name like JTimber15 or FatOne3, or Sleepy, or Curly, or Psycho, or any name or nickname that is easily associated with N Sync. If JC was really gonna come online and talk to someone, he wouldn't do it with the screen name "SleepyChasez."
5. Don't blatantly announce "I'M CHRIS KIRKPATRICK! WHO WANTS TO TALK TO NSYNC?" Keep it subtle. Use small little hints about who you are, such as "oh, hang on, our little dog is running around. Gotta get him back in his cage." or "I miss driving my beautiful car." Eventually, someone will catch on and IM you. Then, you have them hooked.
6. It's often easier to pretend you know them, rather than actually being them. But make sure you have a story that's believeable. "Oh, I met them at a meet and greet and now I travel with them" is not gonna cut it. Think of family members that could've possibly introduced you. That's a safe method of claiming you know them.
7. Important personal facts are key. Know parent's names, sibling's names, birthdays, favorite colors, etc. Only the real guys are gonna ask you questions that you can't find the answers to in BOP magazine or the Official Book.
8. Interesting new fact, courtesy of BB magazine's October 1999 Issue. It turns out that JC always has his laptop with him and spends most of his downtime on the internet. Therefore, it would make more sense (JUSTIN posers) to pretend to be JC, and he is the more likely to be lurking in the N Sync chatroom on AIM.
Okay, I think that's all you need to know to successfully fool the teenyboppers. If I think of anything else, I'll update it! Until then, enjoy messing with 12-year-olds!!
