Beware the snowman

WCK asked why people get headaches when they eat ice cream. I explained that when you eat something cold really fast, the blood vessels in your head suddenly get really cold and clench up, blah blah blah. (I checked this later on Wikipedia, and it turns out I was pretty much right.)

WCK said, “Oh, kind of like when you’re all warm and cozy and then a snowman suddenly jumps on top of you?”

Yes. Exactly.
