Bought a pack of Orbit Lemon-Lime gum. Opened it, got a whiff of the stuff, immediately thought of dish soap. It's mostly lemon, but it seems like there's a touch of mint/menthol in there, and that really pushes the flavor into the realm of detergent.

I wish companies would stop using food fragrances for their non-food products. Two of my favorite scents are practically ruined: lemon is "what soap smells like", and vanilla is about to become "what a candle smells like".
