Urgence de feu

I was thinking for hipsters in French-speaking Switzerland and in the Haut-Savoy region of France, one could adapt this T-shirt design

to one that takes advantage of the local fire-roasted culinary specialty, raclette

To wit: "break the glass to get a wedge of cheese and some potatoes."

Even though people usually use a machine nowadays to make their artery-clogging treat, rather than open flame, I think the gag would likely get across anyhow.
