A quick McCarver saying...
"David Eckstein, like most players, has 20 digits. 10 fingers, 10 toes. He used them all on that play".
My favorite Joe one from recent memory
R1, R2. 1 out. Deep fly ball to center. U1 sprints out to get the ball. U2 lines up the tag, U3 awaits at 3 and PU at home. Both runners end up tagging, but R1 stops and gets thrown behind at first. U2 has to make a close call on R1 from the saddle.
Joe says that he has umpired for years, and that U2 needs to run out in this situation, not U1. Furthermore, if U1 goes out, then PU should come up and get 1st base.
Where does he come up with this stuff?
