Fanfare of Strumpets

A group of academics is coming home late at night from dinner when they meet, coming in the other direction, four ladies of the night.

One of the academics says, "Ah, a bevy of beauties!"

Another from the English department says, "No, I'd say it was an anthology of prose!"

The third one, who's also from the English department, says, "No, an essay of trollops!"

A chap from the law faculty says, "No, I'd say it was a firm of solicitors!"

And finally the chap from the geology department says, "No, I'd say it was an outcrop of ores!"
