Kim Kardashian hocked her QuickTrim diet system on The Tonight Show with Jay Leno, but she ended up spending most of her time teaching a guest how to properly toast.

Kim is the face of QuickTrim, a series of products designed to help lose weight. She appeared on the Tonight Show to talk about it, showing off a svelte figure in a tight outfit.

However, before Jay Leno and his prior guest Dana Carvey could try the drink (after assuring them it wouldn't give them diarrhea), she was adamant that Carvey get the toast right.

Her rules included looking in the eyes of the person you are toasting with, producing a good sound when "clinking" glasses, and holding hands. She believes that otherwise toasters are doomed to "several years of a bad sex life."
