Let's start a rumor...
Some Oreo cookies have a rainbow imbedded in the filling. The rainbow is a mixture of compounds which will instantly trigger a desire to change your gender, but only if you are cisgender. The only way to avoid a rainbow is to twist the cookie apart and inspect the filling before eating it. It is rumored that dunking the cookie in whole milk (skim, 1%, or 2% will not work) may deactivate the rainbow, but so far no one has been brave enough to test the theory by eating an untwisted whole-milk-dunked rainbow Oreo cookie. Be safe out there, twist your cookies.
