I heard a program on the other day.
Some guy was trying to tell a caller who asked if Jesus was
killed on a cross or a tree (because apparently the later is
Jewish law), so he said a tree & a cross are the same thing.
Not so:
If weebles are wobbles & wobbles are wubbles, does that
make wubbles weebles? Of course not!
So you can say a cross is a tree, but not the other way around.
And

to anyone who denies logic!
