You're pissed off your buddy list can only hold 200  names

You begin to say hehehe instead of laughing

You can now type over 70 wpm

You type messages to people who are right next to you or on the phone with you.

You sign on and immediately get 10 messages from other people

You have a few screen names, some of them secret.

Your screenname has the year 1997 or earlier in it.

You don't break for the bathroom - even though you've got to go real bad - until you think of a witty away message.

You have a few people on your buddy list just to spy on them.

You've had a meaningful conversation with a bot.

You learned Photoshop to make a super cool avatar

You have the Yahoo Toolbar and your home page set to Yahoo

You have every chat client that can connect to Yahoo,just so you can have 5 screennames in the one room

You actually get these jokes and pass them on to other friends who are addicted to Yahoo
