14 people played the round. Interesting answers all around!
Name one of the Ten Commandments
For 10 points: (and I'm going to abbreviate these...)
Thou shalt not take the name of The Lord in vain, Thou shalt not steal, Honour thy father and mother, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt have no other gods before Me, Thou shalt remember the Sabbath and keep it holy.
5 points: Thou shalt not bear false witness against thy neighbor (3), Thou shalt not covet thy neighbor's house or wife (3).
One had to be pitched: the Fifth Commandment (not a real answer

)
One of Tsar Nicholas Romanov and Alexandra's children
For 10 points: Alexis & Anastasia
5 points: Maria (2), Tatiana (4) Olga (5)
Oh, and yikes---one player answered GeorgeV (obviously not acceptable)
One of the victims of The Challenger disaster in 1986
For 10 points: Michael J. Smith
5 points: Judith Resnick (2), Gregory B. Jarvis (3), Ronald McNair (3), Elison S. Onikuza (5)
German Days Of The Week
Note: first of all, I confess to having misled you all a bit. There are actually 8 correct answers, not the 7 I suggested...
For 10 points: Sonntag, Montag, Sonnabend (that last one is the one I forgot about---just a different way to say Saturday over there), Samstag
5 points: Donnerstag (2), Freitag (2), Mittwoch (6)
Original "Saturday Night Live" cast members...
And here I thought this would be the easiest for me but it turned out to be the hardest one to verify. Because of the way my question was worded I had to give credit to Albert Brooks because he did have a recurring role (as himself) that first season. Refer to
www.imdb.com to check if he was really on the cast list. It says he was. So:
For 10 points: Albert Brooks (that rascal

), John Belushi, Garrett Morris, Gilda Radner, Dan Ayckroyd
5 points: Chevy Chase (2). Jane Curtin (2), Laraine Newman (3)
Two answers were incorrect:Jim Belushi (John's brother) came on the show later as did Chris Farley.
