Being a fan of R/C cars I have come across the perfect toy to annoy people with. A tank that shoots BB bullets and you have two sizes to choose from.

Realistic treat, full rotation of turret and 20 degree movement for vertical aiming. The bullets can be a single shot or multiple shot at one every second. This can be a very dangerous but entertaining toy, I would go into battle against kids, and small creatures of the neighborhood. Who is up to turn the office cubicles into a battle zone.
