892: So... White...
Introduce a pair of elves who own an albino tiger. These elves wear white tights and loose white shirts, and are generally flamboyant. And as they are spellcasters, when it comes time to cast anything they look at each other and say in tandem, "It's magic time!"
Maybe this is just me, but those two have freaked me out ever since I saw a skit on Mad TV. "Siegfried and Roy: Magicians on the Street." A mix of cop shows and magic shows. Two images stayed with me. The first was the two turning to face the camera and smiling so very... suggestively. The second was a scene where the duo are riding through the streets in a motorbike with a sidecar, and Siegfried says, "It's freezing out here, Roy, my neeples are all hard!"
Just use that sort of thing. The more ridiculously camp the better. Just don't forget to DM the cheesy, suggestive, sinister grin every time the duo shows up. All right, so it's silly... but even silly has its sinister side, and soon you'll be able to scare players just by smiling at them.
Bonus points if you grin broadly while roleplaying another, unrelated character (like the gruff bartender at the Red Dragon) and the players actually look for 'those elves'.
Bonus points if you grin broadly at any time and the players take a collective step backwards.
