This cartoon from Bill Nye Saves the World uses various ice cream flavors as part of a hysterical analogy on the intolerant views of Christians when it comes to sexuality.
It starts off with various flavors of ice cream showing up at an "Ice Cream Conversion Therapy" group. Vanilla is the dogmatic leader of the group. "It's the science of feelings, and as vanilla, I feel that I am the most natural of the ice creams. And therefore the rest of you should just go ahead and also be vanilla. It's the one true flavor."
But his stance immediately weakens once he gets a quick lick of salted caramel, and then all hell breaks loose (literally, if you're a vanilla thinker) as they all jump into the bowl together and vanilla sees his true inner flavor.
