That's it, Mr Organ, keep partying like it's 2018! 
Here's what Mr Oswald actually said:
Nice cherry pick. Here's what
just two of the officials who heard what Oswald said wrote:
"In talking with him further about his location at the time the President was killed,
he said he ate lunch with some of the colored boys who worked with him. One
of them was called "Junior" and the other one was a little short man whose name
he did not know. He said he had a cheese sandwich and some fruit and that was
the only package he had brought with him to work and denied that he had brought
the long package described by Mr. Frazier and his sister."
"He said he ate his lunch with the colored boys who worked with him. He described
one of them as "Junior," a colored boy, and the other was little short negro boy.
He said his lunch consisted of cheese, fruit, and apples, and was the only package
he had with him when he went to work."
— Thomas J. Kelly
This doesn't sound like Oswald was anywhere near a lower floor ...
"You see, I assumed that obvious questions like that had been asked in previous interrogation.
So I didn't interrupt too much, but he [Lee Oswald] said, "Send the elevator back up to me."
Then he said when all this commotion started, "I just went on downstairs." And he didn't say
whether he took the elevator or not. He said, "I went down, and as I started to go out and see
what it was all about, a police officer stopped me just before I got to the front door, and started
to ask me some questions, and my superintendent of the place stepped up and told the officers
that I am one of the employees of the building, so he told me to step aside for a little bit and we
will get to you later. Then I just went on out in the crowd to see what it was all about." And he
wouldn't tell what happened then."
— Harry D. Holmes; April 2, 1964
Notice the Oswald lie: "denied that he had brought the long package described by Mr. Frazier and his sister"?
