What are some different ways I can use many fresh lemons?

Response:
If you have multiple lemons and want to use them before they go bad, consider the following uses: 
1) Lemon cleaning spray. Mix 1 parts water, 1 parts white vinegar, and the juice of one lemon into a spray bottle. A great non-toxic cleaner for around the house!
2) Limoncello. Add 1 cup simple syrup to 4 cups vodka and pour over the peels from 12 lemons. Leave in a sealed glass container for 30 days. Serve over ice and enjoy. (Drink responsibly!) 
3) Lemon flavored olive oil. Slice 4 lemons and put in 4 cups of extra-virgin olive oil. Leave in a sealed container for 30 days. Enjoy in salads and soups!
4) Lemon bars. There are many ways to make these using all parts of a lemon. Check online for a recipe to make these deliciously tart bars. 
5) Lemon-aid. Mix 1 parts fresh squeezed lemon juice to 6 parts water. Sweeten to taste. Serve over ice 
6) Lemon Centerpiece. Brighten up the room by arranging lemons in a decorative bowl. Place on the table or counter to add a pop of color.
7) Lemon Detox water. Start your morning with 16oz of warm water, the juice of one lemon, and a pinch of cayenne.
