Here's a so-called lawyer joke. I don't get it. Can you help? Thanks!
Q: What do you call a smiling, sober, courteous person at a bar association convention?
A: The caterer.
I thought it meant only the lawyer who acts courteously in front of others can do dishonest or evil deeds without getting caught, that is, a 'smart' lawyer need to be cunning enough to disguise themself so as to gain others' trust while waiting for a chance to stab others in their back. But I'm not sure. Maybe I misunderstood the caterer to be a figure of speech, someone who treat others as food, which they can decide how to cut or eat.
