think up a awsome but impractical thing

[Sporky111]

Scissors with high-powered lasers for blades.

 

[Nairang]

well a portal gun would be nice or a TaRDiS a maybe magic taht would be kool too

 

[ReaperzXIII]

Wings made out of laser beams ala Code Geass Knightmares

Confetti bullets! Celebrate the death of everyone you kill!

 

[Marmalade]

I thought of this a long time ago, chocolate pants.

 

[SuperSuperSuperGuy]

A flamethrower that shoots bees that all have rocket launchers that shoot pies which explode into a cloud of nunchucks that are made of miniguns that are attached to chainsaw bayonets with chocolate chains. Did I mention that this flamethrower is mounted on a giant, winged were-tiger shark that's half robot and 1/4 alien invader that speaks like Christopher Lee and exhales acid with lava as blood?

Also, a watermelon is involved. I don't know what's going to be done with it, but it's gonna be AWESOME!

Wow, that was needlessly long...

 

[GrinningManiac]

A giant space cruiser based around the design of an 18th Century Pirate Ship

It'd look Da Bomb, but it'd be pretty rubbish as a life-supporting platform in the hellish void of space

 

[Evilsanta]

This.

OMG! This has to be the most awesome and impractical weapon ever!

OT: Umm...A nuclear powerd flashlight.It will blind you!

 

[Lt.Snuffles]

A catapult made of rabbits and cheese. It's jet powered as well and comes with a threatening looking red button.

 

[BENZOOKA]

A girlfriend with an understandable logic.

 

[FoolKiller]

A "Sex-Bomb"... yeah you read right.
It feels like having sex when hit by it, but you get AIDS.

Sounds amusing but you have misnamed it completely.

There is already a sex bomb and, well, just here...

[randomsix]

A bullet with a capsule of antimatter in it. Bullet impacts, antimatter contacts matter, pure release of energy ensues.

 

[ethaninja]

A Bear Chainsaw. It has bears instead of blades.

Like this?

 

[Jedamethis]

A Bear Chainsaw. It has bears instead of blades.

Like this?

Needs more teeth and claws.

 

[Dapsen]

A gun that shoots water! It'll look like a gun, so that when you point it at someone they get really scared, but when you pull it, they just get a little wet and SUPER embarrassed because they got scared.

I'll call it a WATERGUN!.. Oh, wait. Never mind...

 

[vallorn]

Rocket-powered bacon.

Can you imagine a world with hover bacon?

 

[DesiPrinceX09]

A car with an engine that runs on blood that has been infected with HIV and an outer body made of moon rocks and wheels made of plutonium. You turn it on by reciting yo mama jokes in Latin and it gets a speed boost from rockets that shoot out shoop da whoop lazers. Oh and the gear shift is a deer antler and the pedals are captain hero sandwiches.

 

[Edorf]

A Bear Chainsaw. It has bears instead of blades.

-Snip

Needs more teeth and claws.

Your bearchainsaw as ordered!

 

[ReaperzXIII]

Tactical Nuclear Acne Strikes! They destroy acne and just about everything around you!

A real life pokemon. And you all know why.
