Institutionalized
A new Ph.D. in algebra gets a temporary position at a university for a year. He bumps into one of the faculty and, having the cockiness and arrogance of youth, says to him, "I have heard it said that all logicians go insane. Why then did you decide to study Model Theory?"
"My dear doctor, very few logicians go insane but the entire algebra faculty is seeing the psychiatrist," replied the logician.
Thusly tempered, the young man replies uncertainly, "The entire faculty?"
"Yes, they're all in group therapy."
