1.   At his Connecticut home, Blass bumped elbows with Kissingers.

2.   Add as much as you think proper, and then bump your elbow a couple of times for good measure.

3.   I kept bumping my elbow into the wimpy, poorly placed armrest as I made sweeping turns.

4.   When setting the table, always leave enough space between diners so guests do not bump elbows.
