(other variants exist) In a current campaign in RttToEE, one PC bought some draft horses to pull a cart we were using for a variety of reasons (bait, hauling treasure, etc). A random encounter resulted in the party being attacked by griffins. They went after the horses, then attacked the PCs as we tried to fight them off..."Save the Horses!" Due to the vagaries of bad rolls, the PCs took significant damage, while the horses were virtually unscathed. However, to protect his investment, the PC that bought them made sure the horses had their wounds attended to first- the front line fighters got the dregs of the available healing. Subsequent encounters had similar results. Since then, any encounter in which the horses are even GLANCED at results in some kind of rallying cry to protect them...and they are pampered as if they were Arabian Stallions.
Where are the OREO COOKIES?
In a defunct RIFTS campaign, one of the players wasn't paying attention when, while the party was split, one group of PCs achieved the desired objective (let's call it the McGuffin) and the message is relayed over the party's agreed upon radio channel. Because he wasn't paying attention, he had his heaviy armored PC burst into the camp's mess hall and threaten the staff looking for the McGuffin, which, of course, they didn't have. One NPC fired a small sidearm at his PC (which had 0% chance of penetration), and he opened up full-autofire, shouting "Where is the MCGUFFIN? Give it UP, M****R F*****S!", but rather unintelligibly (like Jeremy Irons in
D&D: the Movie).
The players then point out that the McGuffin has already been recovered and that everyone else was on their way out of the camp. Why, one player asked, was he shooting up the mess hall looking for the objective after it had been recovered? He stammered...
I then suggested that the latino mess hall crew (we live in Texas- Mexicans are ubiquitous in our dining establishments) who survived their encounter with the heavily armored nutcase would be telling stories about the "Gringo who had smoked so much loco-weed that he got the munchies so badly he shot up the mess hall looking for Oreo Cookies." - with a strong Cheech Marin/Stoner accent. We laughed so hard we cried...the guy whose PC did the shooting fell out of his chair and crawled away from the table, gasping for air.
To this day, "Where are the OREO COOKIES?" is a show stopper.
