Thanksgiving Trio

Three Thanksgiving Jokes:

Last Thanksgiving, I had my chance to do the traditional thing of shooting my own turkey.
Man, you should have seen the people scatter in the meat department.

When everyone at the table takes turns saying what they are thankful for, say,
“I'm thankful I didn't get caught,”
and refuse to say anything more.

Keep your eye off the turkey dressing. It makes him blush!

Heinrich Ludwig d' Arrest

Born 13 Aug 1822; died 14 Jun 1875 at age 52.Heinrich Ludwig d' Arrest was a German astronomer who, while a student at the Berlin Observatory, hastened the discovery of Neptune by suggesting comparison of the sky, in the region indicated by Urbain Le Verrier's calculations, with a recently prepared star chart. The planet was found the same night. His father-in-law was A. F. Moebius (1790 - 1868). d'Arrest found several comets, the one of 1851 with a period of 6.6 years bears his name. One work he published was on the Asteroids between Mars and Jupiter, another work titled Siderum nebulosorum observationes Hafniensis contained 1942 nebula, 340 described for the first time.[DSB gives date of birth as 13 Aug 1822. EB states 13 July 1822.]
