When Joe DiMaggio broke in with the Yankees in 1936, he hung out with Tony Lazzeri and Frank Crosetti. All three were of Italian descent, all three were from San Francisco, and all three were notoriously quiet.
One of their favorite "activities" was lobby sitting, which was exactly what it sounds like: Sitting in the hotel lobby watching people come and go. Lobby sitters didn't converse; they sat.
A reporter one day saw the trio taking their place in the lobby and, with nothing else on his agenda, decided to time their silence. A half hour dripped by without a word, then an hour.
An hour and 20 minutes in, DiMaggio coughed.
Crosetti said: "What did you say?"
Lazzeri said: "Shut up. He didn't say nothing."
They lapsed back into silence. The writer gave up about 10 minutes later; it was making him crazy.
