Working with Frankenteen

I have a coworker that some of us lovingly call Frankenteen.  Ok, by "some" I actually mean "two", but that's beside the point.  He's a funny kid and will just swoop past my department, grab candy out of the candy dish, pop my bubble wrap, then swoop back out again with a "Hi! .... Bye!"  This is an actual conversation that took place during the company's busiest week of the month.  To set the stage, my desk was absolutely buried and I was frantically trying to get as much done as possible when Frankenteen came bounding into my section.

Frankenteen: Are you busy?

Me: Uh... yeah... just a bit!  What do you need?

Frankenteen: Can I use you as a test dummy?

Me: ...for what?

Frankenteen (pointing at my computer): For that!

Me: What do you need to do?

Frankenteen: Don't worry, it won't effect your work! We just need to test something!

Me: What do you need to test?

Frankenteen: I need to check to see if you have admin rights.

Me: I DO have admin rights! I already know that I do so you don't need to check!

Frankenteen: Oh, well we can't use you then. Bye!
