Public bathrooms are becoming an increasingly popular target for advertising. The latest is a guerrilla bathroom campaign to promote the second season of Dexter on the FX channel in Portugal.

The campaign uses a blood-red dye in urinals to produce a blood-like flush. The campaign catches people off-guard (literally with their pants down) and stays true to Dexter's trademark of excessive blood and gore.

Watch the above video for a demonstration of the ambient campaign in action.
