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.'

William D. Phillips

Born 5 Nov 1948.American physicist whose experiments using laser light to cool and trap atoms earned him a share of the Nobel Prize for Physics in 1997 (with Steven Chu and Claude Cohen-Tannoudji). They developed methods to use laser light to cool gases to the microkelvin temperature range near absolute zero, and keeping the chilled atoms floating or captured in different kinds of “atom traps”. The laser light functions as a thick liquid, dubbed optical molasses, in which the atoms are slowed down. Individual atoms can be studied there with very great accuracy and their inner structure can be determined. As more and more atoms are captured in the same volume a thin gas forms, and its properties can be studied in detail.
