An Urban Myth states that this shrinks your testicles.

Not to be confused with Maroon 5.
Samantha: "Why are you drinking that Mountain Dew, don't you know it has Yellow 5 in it?"
Andrew: "Do you honestly think they would sell a product that shrinks your testicles and not even put a warning label on it, or even sell something like that at all?"
Samantha: "Oh... I never thought of it that way"
