I recently sent off a bundle of riddles to popular riddle-mag Riddler's Digest. They rejected all my riddles so I thought I'd publish them here:
1) What can (but not necessarily is) be made of wood, and is the piece of furniture that you'd traditionally eat your dinner from (although it's becoming more common to eat it off something like a breakfast bar, or straight out of the oven in fact, I think that's getting quite common) ? They have other purposes too: e.g. snooker, craps (the game) and a mountain in Africa
BUT they don't swim or talk (amongst many other things).
2) It has three prongs and it's often silver (not a trident, but very similar to one, in terms of shape).
3) Often referred to as 'a cat'
