A lemon. It’s a citrus fruit whose juice is acidic and can be used to conduct electricity for motors. A car or other purchase that has problems is known as a lemon and can be expensive to repair. Lemons have a tart flavor but do little harm (unless you get it in a cut, then it hurts like the dickens). The old saying goes, “When life gives you lemons, make lemonade” (I know, it’s spelled aid not ade but it sounds the same and wouldn’t make any sense the other way. It all works out nicely when the riddle is told instead of read.)
Frog. It only has four letters, removing the “r” leaves fog, which makes it hard to see. Changing the “r” to an “l” makes flog, a punishment I hope you’ve never experienced. Flog backwards is golf, a game some would call a punishment when you keep swinging away at the ball yet it remains perched on its little white tower of terror while the other golfers impatiently wait for you to tee off.
This is a place. The first letter is after A and before Z but nowhere in between. You can bring as many people as you want, as long as they’re all dead. Where is it?
The cemetery. The letter C is after A and before Z, and it’s not found in the word “between”. The cemetery won’t take live ones. Fortunately I don’t speak from experience on that.
