Restroom Talk

I was barely sitting down when I heard a voice from the other stall saying: 'Hi, how are you?'
I'm not the type to start a conversation in the men's restroom, but I don't know what got into me, so I answered, somewhat embarrassed, 'Doin' just fine.'
And the other guy says: 'So what are you up to?'
What kind of question is that? At that point, I'm thinking this is too bizarre so I say: 'Uhhh, I'm like you, just traveling.'
At this point I am just trying to get out as fast as I can when I hear another question. 'Can I come over?'
Ok, this question is just too weird for me but I figured I could just be polite and end the conversation. I tell him, 'No........I'm a little busy right now!!!'
Then I hear the guy say nervously...

'Listen, I'll have to call you back. There's an idiot in the other stall who keeps answering all my questions.'

Godegroy Wendelin

Born 6 Jun 1580; died 24 Oct 1667 at age 87.Flemish astronomer and clergyman who was known as the Ptolemy of his time. Despite going against the tenets of his Church, he was an audacious proponent of the Copernican theory that the planets orbit around the sun. He made more accurate measurements of the distance to the sun as previously made by Aristachus (2,000 years earlier) from the geometrical relationships at the exact time of a half-moon. His result was a third smaller than now accepted, but still indicated the order of magnitude. From his studies the motion of a pendulum, he observed that as amplitude is increased, there is some increase the period of the swings. He noted a temperature effect on the period of a pendulum: more oscillations in winter than in summer. Wendelin is regarded as first to formulate a law for the variation of the obliquity of the ecliptic. Newton cited him in his Principia.«[Latinized name: Vendelinus. First name variations: Godefroid or Gottfried.]
