Pull up at stoplight, singing loudly to radio. Make eye contact with driver in the next lane just in time for us to simultaneously hit "Scaramouche! Scaramouche! Will you do the fandango?!" at the top of our lungs. We nod and smile a silent "well done, sir" to each other, light changes, off we go. Feel bad, though, that we're not stopped at same light a few minutes and blocks later when "Layla" comes on; I think we could have made beautiful music together on air guitar.
