I bought a new phone today, and verizonwireless.com has this chat feature where some support person will help you through your order.

I decided at the end to mess with her, it wasn;'t my best work:

You: seems like everything worked out
You: oh wait
You: ... what the.
Jordan.: Yes?
You: it says it cost 50,000 dollars!!!??
You: it charged 50000 dollars to my card
You: oh my god
Jordan.: Where do you see that?
You: in the confirmation!
You: what kind of god damned business are you running here
You: i'm going to sue this company all of it's Freaking money
You: how could you do that?
You: ANSWER ME
Jordan.: This may be a site error.
Jordan.: I do not believe that was charged to your card.
You: you don't believe?
You: well i BELIEVE THAT YOUR COMPANY IS SCREWING ME
Jordan.: I'm going to give you a phone number where they can view the order.
You: i'm sorry i'm just joking
You: april fools joke
You: gone a little too far
You: haha
Jordan.: LOL
Jordan.: You really did scare me.
