Wikipedia: Wikipedia
Wikipedia (/ˌwɪkɪˈpiːdiə/, /ˌwɪkiˈpiːdiə/ WIK-ih-PEE-dee-ə) is a multilingual, web-based, free-content encyclopedia that is based on a model of openly editable content. It is the largest and most-popular general reference work on the Internet, and is named as one of the most popular websites. It is owned and supported by the Wikimedia Foundation, a non-profit organization which operates on whatever money it receives from its annual fund drives.

Wikipedia: Pedialyte
Pedialyte is an oral electrolyte solution manufactured by Abbott Laboratories and marketed for use in children. It was invented by Dr. Gary Cohen of Swampscott, Massachusetts.

When I want everyone in the entire world, despite their limited intellectual ability, to help me cure my hangover, I drink Wikipedialyte.

Hey, kids, drink Wikipedialyte. It replenishes bodily fluids unexpectedly discharged when you realize you need to do actual research!

Just drank some Wikipedialyte. It may be full of nutrients, or that info could just be made up.

If the child dehydration remedy ‘Pedialyte’ built an online knowledge base, they could call it “Wikipedialyte”.

Thinking of starting a crowd-sourced web site about children’s vitamin beverages. It will be called Wikipedialyte.
