Please pass the Grey Poupon

Reese loves mustard! She obviously got this from her father, because I hate the stuff unless it is mixed in with something else (like my aunt's awesome potato salad). Anyhoo, Reese loves mustard, but unfortunately cannot pronounce the word. Whenever we have mustard at the dinner table, she says, "I want some muster!" We may have to teach her the catchphrase of the 90's, "Please pass the Grey Poupon", so that others can understand what she is asking for!
