Human: How can I get rid of a bad smell coming from my kitchen sink? Assistant: 
One way to get rid of a bad smell coming from your kitchen sink is to scrub it with baking soda and vinegar. Mix equal parts baking soda and vinegar in a bowl, then pour the solution down the drain. Let it sit for about 15 minutes before rinsing with hot water. Another option is to try boiling some white vinegar or lemon juice and pouring it down the drain.
