Priceless! (No more caption contests needed... ever)

And some obligatory text from the CNN article because of the 1-sentence rule:

New York's busy Penn Station returned to normal on Friday after a rush-hour false alarm caused by a suspicious substance found in a soda bottle near Amtrak's ticket counter, authorities said.

The scare came a day after authorities warned of a possible terror threat against the city's subway system.

Police closed the station's main entrance and about half of Amtrak's main platform near the place where the bottle was found.

New York Police Commissioner Ray Kelly later said the whole incident "appears to be a prank" and the liquid was "a Drano-type substance," referring to the household drain cleaner.

Open the floodgates- here come the pranks. Well, I'm just glad that my NY subway experience happened 2 weeks ago (boy the March in DC was huge, and fun).
