You can always say, you'd better straighten up, Warp Factor 9.
When I was able to work, I would finish a big project and put it on my boss' desk. He would be reading something and wouldn't even mumble, "Thank you."
Well, one year they came out with Star Trek TNG phasers. Of course, I promptly bought myself one. It lit up, made a phaser noise, and had all the trimmings on it.
One day I finished a huge project and once again, my boss didn't notice. So, I stood right there in his office and said, "Good job, Jan! Thank you very much for all your hard work."
He still didn't answer. I had brought my phaser with me, just because I could, so I went and got it, pointed it at him, and pushed the button. He looked up and saw the lights and heard the noise. I said, "You never thank me for all my hard work, so you've just been phased!"
I got a lot of free lunches out of that one!!!!!!!!!!!
