Impending Doom O'doomness! Squeee!!

Converstations that happen between user/pofessors, while working at the lab 2 minutes before you get off work:

Professor from the lab next door: "Who are you again?"
Me: "The Lab Assistant."
Prof: "Oh, right. Well, I have a problem."
Me: "How can I help you?"
Prof: "Do you have any extra mice?"
Me: Mice? Yes I carry a pocket full of mice with me at all times to feed my snake in my backpack! "Um, no we don't have any extras here in the lab. Why? What is the problem?"
Prof: "It's old and not working! It is one of the mice with the rolly ball on the bottom still."
Me: What? We don't even have those kind any more... (the new lab assistant walks in) "Well, what we can do is have her(the new LA) look at the mouse and submit the problem into our database and have one of our techs looks at it."

The professor goes back to setting up, and two minutes later comes back knocks on door and says "Never mind someone beat ya to it, it is ok!"
Me: "Ok" ya weirdo.
Three minutes later:
Prof knocks on door again: "I lied it is still not working, the scrolly thing doesn't move."
Me: The scrolly thing? to the other lab assitant: "Can you take a look at it? I have to go to class."
Prof: "And I can never remember how to save PowerPoint but the scroll works fine on PowerPoints, all I have to do is click the mouse."

Some days people's brains confuse me.
