Quitting job, and few more jokes

I have decided to quit my job as a personal trainer, because the weights are too heavy.
I just handed in my too weak notice.

My doctor told me I have high blood pressure and short term memory loss.
At least I don't have high blood pressure.

My wife yelled, "are you even listening to me?"
I thought that was a weird way to start an argument.

He designed instruments and mathematical and numerical techniques to improve parallax measurements. He published ten volumes of zone catalogs, including some 150,000 stars. He compiled positions, magnitudes, proper motions, radial velocities, and other data to produce the first edition and, with Louise Jenkins, the second, of the widely-used Bright Star Catalogues, making Yale a leading institution in astrometry.
