Bouncy sniper rounds?

That would be funny... you snipe this one guy and it procedes to bounce hitting and killing all of his teammates....
Firework Rockets- Shoot a rocket, and it swivels around in circles homing in on anything in range.
Laser Turret- Actually, this wouldn't be that crazy. This would be awesome. OK, the laser turret shoots the damage and continious beam of 4 sentinels.
Barney Banshee- Fuel rod gun shoots a costumed dinosaur.
TV Rocket Warthog- Shoots TVs, which explode with an electrical charge, and stun anyone in range for 2 seconds watching hotties....
