The Definition of Irony

I was with my friend last week and I decided to change her cellphone voicemail to my voice saying this:

"Hello?....hello?....HELLO?...WHO IS THIS?.........haha just kidding leave a message." Beep.

And I was laughing & rubbing my hands with evil glee because people kept falling for it and having conversations with the recorded message.

And then I called her today...and I fell for it.

Excuse me while I go hang my head in shame.
