Excuse Me

I got an instant message from one of my co-workers...

co-worker: I NEED YOUR HELP!!! PLEASE!!!
me: ?
co-worker: My zipper broke.
me: [laughing uncontrollably] And how do you want me to help you?
co-worker: I don't know, can you think of something? Maybe you can unzip it?
me: How'd you break it anyway?
co-worker: Do we really have to discuss it now?
me: Well...
