Condiment Gun

Sausages, chips and burgers will be unable to dodge the splodge once you arm yourself with a Condiment Gun. As you can see, this brilliantly ridiculous sauce dispenser looks just like a comedy cartoon six-shooter and it's ideal for anyone who loves squirtable condiments such as ketchup, mustard and brown sauce.
All you do is load up the Condiment Gun's cartridge (two supplied) with your favourite sauce, bung it in and squeeze the trigger. Satisfying? It makes walloping the bottom of a regular sauce bottle seem about as entertaining as watching a tomato go off. (From firebox)

I have to think this will end in nefarious usage.
