Yes, definitely!

A lot of times me and Misfit would run around sending random /tells to people demanding to know why they haven't sent any child support for our poor little baby.

I've actually made a few friends via random /tells.

I think one of the best parts about this game is being goofy and fun with other players. It's something you can't do in any other Final Fantasy game. And it's always a nice surprise to find other players who are just as goofy. As opposed to the players who get all offended and tell you to go away and leave them alone. When you find people who are willing to play along and have fun... well, that's just super.
