I'm driving South through Brookhaven, PA. Suddenly, fire engines and emergency vehicles appear behind me. I pull over and let them pass.
Traffic is usually two lanes each way on this stretch of Edgemont Avenue - plus a central turning lane. It was evidently built for just four lanes, so it's very tight.
Evidently, the emergency vehicles are blocking two or three lanes ahead, because traffic is down to a slowly-moving line. But eventually I get up to where the fire trucks are, at the intersection of Edgemont Avenue and Brookhaven Road.
And the fire...is in...the smoke shop! The big Rebel Indian Smoke Shop on the corner.
I assume that qualifies as irony.
