"Happy Valentine's Day!" Dean exclaimed gleefully, proffering a red envelope.

Sam took it warily, expecting the imminent appearance of a bloody severed body part that would typically accompany the otherwise uncharacteristic gesture.

The card was decorated traditionally with a big red heart. Inside, an untidy scrawl seemed to read, "I HOOT YOU!"

"Is that supposed to say, 'I heart you'?" Sam asked, giving his brother the benefit of the doubt. Big mistake.

PARP! PAAARRP!

Sam started and reeled back, ears ringing, from the airhorn that had suddenly blasted at him.

Dean grinned. "Never say I didn't warn you!"

"JERK!"

"Bitch."
