Sometimes chance bits of conversation make perfect sense.
(Two cyclists) "... so I went right over the handlebars."
Sometimes you're just left wondering.
(Two joggers, one lagging) Leader: "Don't run! Don't run! I'd rather have you in one piece. Don't run!" The laggard starts to pick up. Leader, running harder: "Don't run!"
(Group of cyclists) One: "... improv." Another: "But they're all highly trained in, like, Elizabethan drama."
