When Professor Hart arrived in cavernous Echo Hall to deliver his Plenary Lecture on the Future of the Humanities, he found not the full student body in attendance, not even one student body, but rather a collection of mobile devices positioned to record his voice (meanwhile gregariously buzzing, flashing, and chirping amongst themselves), whereupon he issued an unprintable ad hominem attack against Charles Babbage, Alexander Graham Bell, and Steve Jobs, and thenceforth proscribed the use of anything digital in the lecture hall, an impassioned announcement that was cut short by the Für Elise ringtone of his own iPhone.

At the Plenary Session of the American Psychoanalytic Association's winter meetings, where the world-renowned child analyst Dr. Ernie Humboldt delivered a ground-breaking paper on the Elektra Complex, he was met with some very hurtful ad hominem arguments (for instance, that he took anxiolytics and was quite overweight, so how could he possibly have any scientifically valid insights), causing such embarrassment to the heretofore cheerful and gregarious little man that he retired to his cabin in the Poconos, unplugged his Internet connection, and completely proscribed contact with professional colleagues for six months.

For all its early gregariousness the plenary gathering of the five families of the New York mob quickly degenerated into an ad hominem assault on the character of Bruno Tatallia by Sonny Corleone that became so heated the chairman, Don Barzini, was forced to proscribe the carrying of firearms into the meeting hall; despite his sincere belief in the Second Amendment rights of all citizens.

In proscribing ad hominem soapbox addresses at Speakers' Corner, the authorities were severely censured by a plenary tribunal for infringing the rights of the gregariously suggestible. (by Et Seqq)

When Larry attacked ad hominem Mary's support for proscribing drugs, by recalling her past alcoholism, I realized I had invited a few too many of my friends in my desire to have a plenary birthday party for the gregarious Mary. (by QuaQua)
