We can still vividly remember our first Marx Brothers movie. It was 1974 and, having just turned sixteen, we were given permission to borrow the family Volvo to drive across town to catch a double feature of Horse Feathers and Monkey Business. Horse Feathers opens with Groucho’s Prof. Quincy Adams Wagstaff being installed as the president of Huxley College. Following a longwinded introduction by a stuffy faculty member, Groucho steps to the podium and addresses the assembled students:

Members of the faculty and faculty members, students of Huxley and Huxley students — well, I guess that covers everyone.

I thought my razor was dull until I heard his speech. And that reminds me of a story that’s so dirty I’m ashamed to think of it myself.

As I look over your eager faces, I can readily understand why this college is flat on its back. The last college I presided over, things were slightly different — I was flat on my back. Things kept going from bad to worse, but we all put our shoulders to the wheel and it wasn’t long before I was flat on my back again.

Any questions? Any answers?? [breaks into song] Any rags, any bones, any bottles today …

[bangs a gavel on podium] Who’ll say 76? Who’ll say 1776? That’s the spirit — 1776!

The real reason I came to this college was to get my son out of it. Ah, I remember well the day he left — a mere boy and a beardless youth. I kissed them both goodbye….

And so it went. We were thoroughly and completely hooked — on the entire Marx clan, of course, but especially Groucho. Our prized possession to this day remains the autographed photo we received from him after sending him a birthday card on what proved to be his last birthday.

And we remain as devoted to the boys as ever. If you’re a fan, you know what delights tonight’s marathon holds in store. If you’ve not yet been initiated to the bizarre world of the Marxes, here’s your chance.
