that he dished out after the sunrise thing is an example of his dry humor.
After not being able to answer Wienke's question about it, he tells P. Cooper the sun rises in the "East. Apparently it's well known."
I wondered back then.
The "apparently it's well known" was thrown out there nonchalantly, with no facial expression, but it was funny. Now I think he was having fun with it the whole time.
Ramily!
